I'm sorry, but I find this mentality from app developers extremely annoying.

I personally prefer light themes everywhere, both in IDEs and in the terminal. I thought that just choosing my own color scheme for 0-15 would give me the color pallette that I prefer, but because app developers like you for some reason decided that you know better what colors do I prefer, this is actually not enough. I also have to configure each TUI application separately to have the color scheme that I like.

And I do not understand why people do it. Like, why would you deliberately break the universal customization system and force users to use your own, specific to your app?

Honesty, each time I encounter an app that uses 16-255 colors, I feel like someone just violated my personal space and intruded into my chosen color pallette with their own colors that don't fit.

I'm not an app developper. I make third-party colorschemes for Vim, which I assume are downloaded, installed, and used by people on their own volition, after they have looked at, and liked, the screenshots. Moreover, I take great care to make sure they are still usable in 16c, within reason.

Because all my work is based on 16-255, I can actually guarantee to my users that, given a properly configured terminal emulator, they will get the colors on the screenshots.

If I can't rely on 16-255 to be fixed anymore, then I won't be able to make any promise anymore. In practice, it just means adding a caveat in the README.md, but I'd prefer not to. Here's hoping this breaking change gets hidden behind a checkbox/flag.
