[erlang-questions] Time for OTP to be Renamed?

I'm sorry for adding to a thread so long that the scroll bar on my
browser broke and I had to revert to Mutt.

The C language had for many years a separate set of tools called
"libraries". At some stage a set of these became "standard" and were
incorporated into the ANSI definition of the language. The libraries
still exist, with their original weird names. However we don't speak
of C / stdlib. We speak of C99, perhaps.

It's not about killing OTP and/or changing its name to something
sexier. It's about accepting that this is a standard part of the
language and can be removed from the front of the stage.

Simpler is almost always better.
