I did thanks.
"If you like to tinker with your own system, that’s fine with us ... However, if you change things like stylesheets and icons, you should be aware that you’re in unsupported territory."
Unsupported territory for choosing a distro that looks unusual, or applies theming, or for changing my own damn desktop icon?
Which is then thoroughly buried by a point of view that feels the app is the only arbiter, and tries to justify that on consistency of brand, icons not representing what the developer wishes etc, and that even individual user customisation is a big favour - an unsupported edge case.
What of the users?
It's reasonable to expect an app to both allow, and to work correctly with any theming built into the platform or distro. Bugs may be on either side. I concede it's mainly the major platforms that have done most to take away choices here, so you can no longer download new iconsets - to transform everything into ST:TNG or whatever. Where a distro seeks to theme everything it's the one app that won't, for brand experience, or developer wishes - that now sticks out like a sore thumb.
That is to be regretted, as much as platforms removing ability to build a custom night mode or extreme low contrast theme, or even add some slight 3d back to Windows. It's the end user who loses out to a worse experience or usability each and every time.
Changing the UI changes the software from the user perspective.
