Ah, right, that makes sense.

As long as we only redistribute these files without modifying them at
all, I think it's fine to have them as-is in elpa.git.

If I were you, I'd probably prefer to split them into a separate
"javascript support for context-coloring" package, but luckily I'm not
you, so feel free to do as you wish in this regard.
