I'm not sure what my concern is; I'm just curious. :-) I guess my
inchoate attitude (as an interested observer who has a patch waiting
for approval that adds per-objfile data) is that I don't mind at all
adding new data to every objfile: there just aren't enough of them to
worry about.  The advantage of doing that as a member is that its
existence is right there in objfiles.h for anybody to look at.  The
advantage of Mark's mechanism is that, if the data is only used by
one file, then you don't have to clutter objfiles.h with it.

I was also going to write, based on a cursory misreading of Mark's
patch, that it simplified memory management in some circumstances, but
now that I look at it more closely, I think I just misread the patch.
(I may still be misreading the patch; my head is spinning with other
things.)  Would it be possible/beneficial to modify the mechanism to
provide an optional per-datum cleanup function as well?
