I think use cases where you want to unconditionally bash a string together are rare. I'd bet that in > 80% of cases the "just a string" really is just a terrible representation for what really is either some tree (html, sql, python, ...) structure or at least requires lazy processing (logging, where you only want to pay for the expensive string formatting and generation if you run at the log level or higher that the relevant logging line is meant to operate).
If the "just a string" is html, sql, python, etc., the programmer is making a mistake as string interpolation shouldn't be used for those things in the first place, and I really hope < 80% cases of "just a string" are among those.
"just a string" where the string really is just a string is really, really common though. Python is the go-to language for a lot of people (including me) if they just want to bash together a one-time-use script that will never see input from other people, and f-strings are incredibly useful in such cases for generating filenames, debugging messages, etc.
