No, I don't think that's true. Maybe I'm too much on the defensive side 
but I definitely remember several occurences of me having to raise 
concerns about proposed changes, just for the sake of protecting my own 
work. So I don't feel the community at large is over-valorizing backward 
compatibility and really tossing away all propositions.

Unfortunately it's not that simple; my feeling is that several more or 
less informal groups have different visions about Squeak and actually 
fight to impose them. Pharo is one such group having divorced from the 
community because it was tired to fight.

One path out of this confusion would be to have a debate about 
articulating those different visions, compare them and see what can be 
done about their differences. I did try, in my clumsy way, to start such 
a debate, years ago, but it did not work.

That was in 2004, almost 5 years ago:

... and reading today what I wrote almost 5 years ago, I see that I 
don't need to change a word: it's still pretty much the same situation.

agreed.
