Due to fixing bugzilla:70672 and the fact that bugzilla:71621 is stuck in some kind of meta talk and will most probably end up as WONTFIX users now have to create custom skins from MonoBook and/or Vector to have e.g. a decent login and preferences page.
However if you do this for MW 1.23 (LTS) you end up with the autodiscovery warning kinda spamming your server log. The new versions of MonoBook and Vector currently only seem to be available for MW 1.24+. Thus it will be nice to have these backported for MW 1.23 to avoid these continuous warnings and probably to have as skin that will not go berserk directly at the next upgrade. This will be cool to have.
If the current extensions created for MW 1.24 are also usable with MW 1.23 when tagging them accordingly will be great.
Hmm... probably a bug should be filed for this?
