I'd suggest that the better question to ask is:

     "Which versions of which distros do we currently intend OE to work on?"

Given that the revisions of Python for the following distributions are
as follows:

Ubuntu 10.04 LTS - 2.6.5
Ubuntu 8.04 LTS - 2.5.2

Debian lenny (stable) - 2.5.2
Debian squeeze (testing) - 2.5.3
Debian sid (unstable) - 2.5.4
Debian etch (oldstable) - 2.4.4

Fedora 12 - 2.6.2
Fedora 11 - 2.6
Fedora 10 - 2.5.2
Fedora 9 - 2.5.1
Fedora 8 - 2.5.1
Fedora 7 - 2.5
Fedora 6 - 2.4.3

RHEL6 (beta) - 2.6.2
RHEL5 - 2.4.3

OpenSUSE 11.2 - 2.6.2
OpenSUSE 11.1 - 2.6.0
OpenSUSE 11.0 - 2.5.2

This would suggest that using 2.5 features should be ok for the majority
of people. My one area of concern would be those using RHEL. RHEL 6
isn't out yet and v.5 uses 2.4.3 - this wouldn't impact me, so I'm not
overly fussed.

The only other question I can think of is "is there an advantage to
using the Python 2.5 features?".
