I don't think the functionality above would interfere with that in any way. The owner entries ("user:" for POSIX, "owner@" for NFSv4 ACLs) are stored in a different way, and they never have the appended ID. (Besides, why not just "find ./ -user XXX -print0 | xargs -0 chown YYY"?) -- If you cut off my head, what would I say?
