I believe that history suggests that a better approach is "fontify
everything and provide a setting that gives most of them the same
appearance", assuming that the combination of tree-sitter and fontification
is performant enough. This also enables some interesting features that were
tried way back in the days of hilit19 like "transiently highlight
everything of *this* type, but not all types". Somewhat like how isearch
(occur, et al) can highlight literal duplicates, but based on shared
semantic properties instead.

I couldn't tell you offhand if the current tree-sitter performance for
fontification is strong enough for this sort of thing or not, and I suspect
the noverlay branch also has some impact here.

Hope that helps,
