That may be technically true. However, every time I pull in something that uses proc macros it seems my dependency count goes flying through the roof and my compile times go right out the door.
Maybe people aren't using proc macros properly. That's certainly possible. But, that also speaks to the ecosystem, as well.

I have two dependencies (memchr, urlencoding) and one two dev dependencies (libmimic, criterion). I have 77 transitive dependencies, go figure. People like to outsource stuff to other libraries, when possible.
