My bitter experience with handling colors in Emacs is that changes
frequently fix some use cases and botch others. So I'd prefer to make
such changes only where the current results are completely
unacceptable (and I'd be surprised if we have such cases nowadays).

I think it is. Think about what you'd say in the doc string of such a
defcustom. "If non-nil, handle colors correctly, otherwise handle
them incorrectly"?
