Plenty of people have suggested that. I'll suggest it for you now if you like. The modern form of libc is very much against the unix philosophy; traditional Unix had a much simpler libc where many functions were just syscalls; some parts of today's libc were hived off into separate libraries like libm, and other parts like NSS and convoluted DNS resolution frameworks just didn't exist at all.
