Yes, it's beyond many, and people are clearly both willing to write and grateful for easier alternatives. Why celebrate gatekeeping?
And even then, just because I could write a small utility doesn't mean I will, 99% of the time. I think being able to easily benefit from others work is generally great.
The problem isn't a widget in platform native tooling, the problem is there's only going to be one, and that platform is Windows 7 and nothing else (including newer modern versions of Windows).
I don't need to download an Electron app to interact with physical hardware, full stop, WebUSB or not.
Is that where we're at now? That writing a small utility to configure a widget over serial in platform native tooling is beyond us?
