Comment 3 for bug 633692

WONTFIX, createrepo collapses them for repodata which is where the bigger win (for yum) is.

Besides not being much of a win in the actual headers, there are other issues as well:
- the symbol versions present real data that can help protecting against broken builds (think of some older version symbol vanishing on a busted glibc build)
- this would cause --filerequire/--fileprovide breakage (remember rpm collects this data per-file), and even if only highest dependency per file was collected, the there would be "duplicates" as the symbol versions can and do vary between files within a package
- symbol versions aren't reliably sortable in general (glibc-ones /might/ be but I wouldn't bet my life on it) so it'd be a glibc-specific hack, and we're trying to /eliminate/ such things instead of adding more.
