No, you don't understand.

There should be no "catching up" involved.  Gecko currently supports 
both "transform" and "-moz-transform".  But these libraries _still_ break.

Furthermore, they will likewise break for anyone else who implements a 
property called "transform".

And as a result, users can't use websites.  Web developers are trying to 
author sites, and those don't work.  This is not a theoretical harm here.

If their syntax changes there is no problem.

Note that I'm not suggesting we blindly ship unprefixed stuff.  For 
example, we're shipping unprefixed @supports right now, but there is no 
problem, because it's not enabled by default.  This is likely to be the 
model Gecko follows from now.

Yes, and we should all have puppies and Unicorns.

You clearly didn't read my original mail.  Please do go do that now. 
I'll wait.

No one dropped anything.
