I'm not sure what exactly you mean by a "registry".  Could you please
elaborate?  I'm only familiar with MacOS's Finder database, which is an
obscure way to associate executable files with four-letter application IDs.

There are times when I *really* would like to have a way of storing snippets
of meta-information about a file (that is, EAs):  I usually have lots of
symlinks as shortcuts to all sorts of places in NFS, AFS and alex.  Since
following them can be very slow (in particular links to distant points in
AFS and alex), I don't want my file manager or directory walker or whatever
to follow those links just to stat the file and see what's there.  But
a unix symbolic link doesn't even tell me if it points to a file or a
directory (unless I explicitly remember to include a trailing /).

Perhaps that is the best use for EAs -- information that isn't absolutely
necessary about a file (such as type or comments), but makes things nicer
and faster.
