Not really: It might be one time calls, so a time based rate limit might
exclude apps which get executed in a row.
Maybe some thread->deprecated bitfield which rate limits the deprecated
warning per caller would be an alternative solution. We should not have
more than 32 of such deprecated functions at once. Of cource it would
still spam the logs when high frequency forking servers use such
interfaces, but I think the probability is low.
