I agree that if we had the opportunity to invent regex APIs from scratch
now, all 4 syntaxes (literals, wildcards, basic regular expression, extended
regular expression) would be worth supporting equally.

But the fact is that POSIX standardizes the regex API, and therefore there
is a border between "in glibc" and "outside glibc". Functionality in glibc
is available at no cost; functionality outside glibc requires additional
link options and increased startup time or a 50KB bigger executable.
