Let us take a look at the versions of some (more stable) distributions:

Debian squeeze (to be old-stable from May 5): 4.1.5(1)
Redhat 5: 3.2.1

While I am all for backwards compatibility (which does not hold here
anyway), discussing bash version 2 seems quite esoteric to me. The
others are supported anyway and nobody had problems yet.
