Thanks for your concerns! Of course we worry about that too, and are
trying to make merging Do The Right Thing as much as possible.

Well, your statements are true in general, but they'll only be helpful
if you give specific examples. Which is more work, of course; it's
also the only way to get constructive results.

No. Better merging is something Subversion has needed for a long
time; it's an area where we lag behind other version control systems
(both proprietary and open source). We need it.

While there are certainly corporations that want to see the feature
finished, and some of them are helping to develop it (e.g., CollabNet,
Google, et al), I don't see commercial pressure causing any problems
here. The community is setting the deadlines and making the technical
decisions in public forums, as always.

I too am worried, but mainly about technical issues that I think are
fixeable (e.g., issue #2897, etc). Can you be more specific?
