That's all true, but people will publish them anyway, so the tools need to defend against them no matter what the protocol says. Based on what I've seen, pairs of colliding tags appear innocently, larger numbers don't, so you set the limit in the single digits. Is it really so much harder to write code that allows, say, three signatures and three IDs than code that only allows one? As I hardly need point out, the process cost of changing the protocol is high, and it will take approximately forever for the long tail to notice.
