We pictured the rate limit (if implemented) as per connection, not for the whole stack, which is what Gerrit has done. If the rate limit is considered too expensive it's fine to take out, of course; it is only a SHOULD.

RFC 4340. 7.5.4 says that this rate-limiting is a SHOULD. I had similar
thoughts in mind regarding the overhead that this mechanism incurs. That
is why it is kept as simple as possible. Something like xrlim_allow is
already too complicated (cf. comments).
