I agree with @evelez7 that the specific styling should likely be gated on a flag. Further, while I want us to be a Doxygen replacement, I dont think we should dogmatically support all Doxygen features. While the styleing here is what Doxygen supports, we should be sure its generally well supported before making it the default. Even if it does become the default, I can imagine projects wanting to opt out, so we'll need a mechanism regardless.
