Comment (by karsten):

 Hmm. I see the benefits of such an API change. And we already have #22678
 that describes something very close, if not the same.

 But should we separate the API change from this fix? In a way, I consider
 it a bug that we're parsing an entire descriptor file before passing all
 descriptors to the application. It's something we should have changed when
 taking out `DescriptorFile`.

 How about I rewrite my patch to not make any changes to the API (in
 particular `DescriptorParser`), and then we discuss the API change,
 including how to do it in a backward-compatible fashion, as part of
 #22678?
