The only downside is now we have to rather tediously tweak the error message texts so they use backticks.

It also dilutes the meaning of color. I've been wanting to see highlighted matches and failures in overload resolution and constraint checks (this has been on my todo list for a while since every attempt so far has failed; as I'm sure you know, it isn't trivial to implement in the current compiler). Such highlights would now have to compete with unnecessary syntax coloration; you can't visually scan for color anymore since it doesn't mean anything special.

Terminal color choices are also painful, though I kinda believe this is the terminal's fault. I ended up doing hacky code in mine to ensure a legible palette, but still, not everyone has done that.

Suppose I, or someone else, were to write a PR eliminating your syntax highlighting in favor of semantic highlighting - colorizing to add more detail about the error message instead of about the lexer's output. Will you accept it?
