I'm sure some people who worked on the N900 and then N950/N9 did just that, but the upper decisions are obviously being made by the same people that thought Windows Phone OS was a good idea... so you're already guaranteed their internal bureaucracy is biased against making good decisions....

While I don't like it as much for aesthetic purposes, I am inclined to agree that a seperate file for a new GLib with fancy voodoo to get different programs using different versions, might be better for the time being.

I don't like it, but if it becomes possible to make the move to truly open Maemo 5, I'm sure a more cleaner setup will naturally follow, but in the meantime working with what we do have is probably better than me insisting that a new GLib break all the old stuff for everyone on the off chance that it motivates updates/OSS-recodes faster.
