This taskish has previously been declined at T200442: Load template styles with a module instead of an invocation on a template page.

This was not a factor when that task was declined, so I think it merits re-evaluation.

A function like the above also enables SyntaxHighlight to make the link clickable similar to require(), mw.loadData() and mw.loadJsonData().

Personally i think this is such a common thing to do, that a standard wrapper makes sense, but i don't feel strongly about it one way or another.

Adding CodeMirror tag since auto-linking could likely be applied to it too, similar to the suggestion for SyntaxHighlight (see T419335: Add CodeMirror auto-linking where missing).

Pardon my ignorance; Is it safe to assume that syntax like { src = 'Namespace:Foobar' } would always refer to the page title Namespace:Foobar?

Otherwise, it may make more sense to wait until we have the new mw.ext.templatestyles.add() method to bring CodeMirror into it. The new syntax would also make it more easy to add autocompletion when typing the page title such that only sanitized-css titles are suggested.

Yes, I was envisioning that we'd only add the auto-linking capability once the new method is introduced. Sorry I wasn't more clear about that!

Although I agree with having a simpler way to add styles since it’s such a common thing, I should note that currently all of those aren’t links either.

Not in CodeMirror, no, but the OP was talking about SyntaxHighlight, not CodeMirror. See https://en.wikipedia.org/wiki/Module:Lua_banner#L-2 for an example of this linking in the wild.

Ah, it doesn’t support cases like https://ru.wikipedia.org/wiki/Модуль:Вложенный_список#L-10 or https://ru.wikipedia.org/wiki/Модуль:NumberOf#L-376 which is why I thought it’s not currently implemented. Apologies.

I created T428952 for this.
