Yeah. I've seen it in BIG production users who really should have known better. People won't see a README in amongst 5000 xlog segments while freaking out about the sever being down. I don't care if it comes as part of some greater reorg or not but I'll be really annoyed if scope creep lands up killing the original proposal to just rename these dirs. I think that a simple rename should be done first. Then if some greater reorg is to be done it can be done shortly after. The only people that'll upset are folks tracking early 10.0 dev and they'll be aware it's coming.
