That is actually one of the strengths of Drupal. Core providing
extensibility, and
not trying to be everything for everyone, and farming out functionality to

Contrib is where innovation happens faster than in core, because the "think
code it, commit it, release it, download it, try it, improve it" cycle is
faster in
contrib. It is not dependent on a few core committers with limited times and

hundreds of tasks to get it in. People who want to try something can do it
and people download and test and improve it faster as well.

The second thing is that there are many arguments of task X be done in a
way, and not another. If core did something just one way, then all the
others will
be precluded without being tried in the field. By providing an extensible
where people extend it in different ways, and "let the market decide" which
one is
better, or even if all of them exist at the same time, everyone wins.

Over time, we continually re-evaluate and move stuff in and out of core as
We pick what has been proven and get it in core, like we are doing with
fields now.
And we send other parts to contrib.

This is the open source way: It does not have to be perfect, just good
enough, and then
released to the community to tear apart, use, extend, remix, borrow,
copy/paste, ...etc.

Think of Linux: it is just a kernel and people take it and extend it, bundle
it, port it
so it runs on everything from cell phones to IBM mainframes to supercompters
many things in between. If Linus insisted on doing a distro early on, it may
not have
been as successful as it is now.
