Well let's not shut anything off in #mediawiki just yet. This has only been
on the list for an hour so let's allow some other people the chance to weigh in :)
Aye. It may be daylight hours in the States, but it isn't necessarily everywhere; some of the people on this list may be sleeping or otherwise unable to read their emails right now. Given the nature of the change (as I'm sure that some people use those feeds), I personally would suggest waiting 24 hours on it.
