I'm all for additional library functionality built on top of what exists that does what you want.

As I said, there are many such libraries out there to do that.

If someone wants to add it to libc, more power to them. I'm not the libc maintainer.

I just don't want conect() to stop working the way it does or for getaddrinfo() to stop
working the way it does.

Since you were hell bent on calling the existing mechanisms broken rather than
conceding the point that the current process is not broken, but, could stand some
improvements in the library (http://owend.corp.he.net/ipv6 I even say as much myself),
it was not entirely clear that you did not intend to replace connect() rather than
augment the current capabilities with additional more abstract functions with
different names.
