Count me in here. It's a large effort to work on a big program, this implies
that it's not easy to change things on the whim to account for the latest
ground-breaking changes in the new version of the toolkit it uses.
I'm all for modernization of a framework, but the rate of forced change would
better be measured in years at least (say, after at least 2 to 3 years
one would then HAVE to use the new infrastructure).
The downside of not being able to go with the newest toolkit version would be
having to work on an old "stable" (whatever that means) version that would
often get unsupported faster than you could say "ouch!", despite all good
intentions to the contrary. Not to mention that having to use the old version
would mean one customer less who's able to work on improving features/stability
of the current, modern version...

Sounds very nice, but that's all just theory and nice words for now ;)
