> One way to enhance the usability of unique identifiers is by making them easily copyable. This can be achieved by removing the hyphens from the UUIDs,
No! That's throwing the baby out with the bathwater! Removing all separators means rare-but-important manual tasks of transcription or comparison become terrible, since there are no clear chunks.
Instead use a different character which doesn't have the same problem, one that most software considers part of the same "word"... such as the classic underscore.
For most people, double-clicking on this 123_456_789 will select all 9 important numbers. (And maybe a trailing space, but that's a separate problem.)
Speaking of which, why are we stuck with this terrible "trailing space selected" behaviour? It's not the case on all platforms, macos/ios perform fine and only select the actual word but Windows still includes the trailing space. There are posts online complaining about this going back 15 years at this point, it's super low hanging UX fruit.
Alas, no... however you might not need a sound if you can use tonal inflections and pauses to express the boundary instead. Particularly when chunks are short and when the receiver (or the software they're typing into) knows the format already... Although with a tech-illiterate relative you'll have bigger problems, like explaining what an underscore even looks like and where it is on their keyboard.
Obviously I can't fully express it in text here, but try to imagine this as a coworker speaking to you: "Hey, write down this IP address. It's ten, seventy, one twentyyyyyTWO, five."
They didn't actually say "period" or even "dot", but I bet you'd type 10.70.122.5 .
I've worked in IT (support, network mgmt and development roles) for 20 years, with colleagues, customers and clients from dozens of countries.
I've never once heard anyone drop out the dots in an IP. Non technical users aren't confident enough to do anything but read it exactly as it appears (one zero dot seven zero dot...) and technical users who are generally experienced enough to know what an IP address is, know that the dots are meaningful.
If it's something like 56.7.23.231, I'm definitely going to disambiguate it by deliberately saying each one of of those three dots.
But if it's more like 192.168.0.1, I'm probably not going to bother with speaking any delimiters in conversation with another person who has at least reasonable familiarity with common IP networking layouts.
Bringing it back to the topic: UUIDs should not ever follow familiar content patterns (if they do, then that's an issue in and of itself), so I'm always going to speak the delimiters of a UUID -- whatever they consist of.
(If nothing else, doing so breaks up the pattern into human-digestible chunks -- which is probably the sole reason we have those delimiters in UUIDs to begin with.)

True, but alas, on iOS I found that a double-tap selected only one of the digit groups.
In my view the touch interface UX is just as significant - perhaps even more so in recent years - given that the backdrop to many of these identifier format decisions is ensuring nontechnical end-user support, under time pressure, over possibly quite unreliable channels, goes as well as it can.
But look on the bright side, at least it didn't try to call the number
BitLocker does this and it's nice UX for walking someone through a recovery key over the phone.
Another VERY nice feature is it hashes each set of 6 digits as you type, so if you transpose one, you immediately get feedback instead of "invalid key!" after typing the whole thing out.
I don't think we're talking about the same problem here.
Regardless of how many dashes you have or how (ir)regularly they are spaced, to select the whole ID you must carefully click-drag-release around its boundaries, you can't just double-click anywhere in it to select.
