The BSD license is actually less restrictive than the GPL, so it's
perfectly valid to release a plugin/theme under it.

It's not acceptable to take existing GPL code (which you did not
write), and release it under a BSD license. But code that you create,
you own, and can release under any license you like. If it's
derivative of WP then it needs to be GPL-compatible only.

Jordi, whether you want to use BSD licensing or not is up to you. BSD
licensing is as close to a no-restrictions license that there is. If
you're comfortable with somebody taking your code and incorporating it
into a closed-source system, then BSD is the way to go. Else, GPLv2
would be recommended.
