I'm fine with having an interface for access to low-level, platform specif=
ic details, but that's not how I have mostly seen $_SERVER being used=2E Mo=
stly, people want specific details, like the requested URL and the HTTP hea=
ders sent, all of which should be trivial for SAPIs to provide in a standar=
d, user-friendly format=2E I wouldn't be surprised if some SAPIs are carefu=
lly mangling the data into fake CGI format, only for userland code to unman=
gle it for actual use=2E

My point was that if we were considering a compatibility break anyway, we =
should look at separating out those common use cases into something higher =
level=2E Having done that, we could even allow the low-level "raw server va=
rs" (not under the name $_SERVER) to drift even further apart, rather than =
sticking to CGI rules from 20+ years ago=2E
