I think it can get to many knobs and confusion in settings. With
system library any feature en|disable
is system  wide so having it as a distro policy is right way to go imo.

good one
hmm yes ipv6 exists already so probably I could reuse that one in eglibc

Its a system wide feature not limited to eglibc if we disable BSD
functions in libc then we better not use them in applications
so this feature knob is the way to handle that for more than eglibc
possibly so are others.
