Native regexp support is preferable IMO. After all - regexps are not
strings. If they were treated differently we’d also be able to have
extra highlighting for things like named groups, quantifiers, regexp
classes, etc. I guess, however, that this would require a lot of work.

Since the regexp syntax can be different between languages, we probably won't get all of that automatically. The direct benefits from the native support I can see is highlighting comments (for regexps with appropriate modifiers, in languages that support that), new faces for regexp itself, and maybe for groups, quantifiers, etc.

The highlighting of the elements inside regexp would probably have to be done the old-fashioned way, in font-lock-keywords (although that code could be shared between many languages). We could implement something like it right now, the main difference is just the lack of standard faces.
