2. Not support multiple <base> elements in either quirks nor standards mode. This would break a lot of pages (36000 in hixies test) for no really good reason since very little code is needed to deal with it.
I don't know if this supports your conclusion, but Hixie's study found 36,000 pages (out of 100,000,000) that *use* multiple <base> elements, but it's not known how many of those actually break if you only support a single base. He mentioned that looking at a smaller subset, it seems most use absolute URIs and so are unaffected.
