My additional suggestions for follow-on RFCs would be: - The filter types could be turned into an enum. Would be a pretty simple RFC. - Get rid of SAPI-side input filters for the superglobals; they complicate code that works with them a bit. The INI option that controls them is already deprecated, so, an RFC to get rid of them completely? I do think ext/filter is kind of weird in that the API is very pre-OO and has a bunch of hardcoded filters and assumptions on how people used the superglobals, but if we have it, it's still worth cleaning up.
