To restate what I said on IRC: things are not breaking because of
SVNKit (they easily support all working copy formats back to 1.3 with
their 1.7 client), it's because of the native clients :-), that insist
on upgrading themselves (nagging the user that there is a new version
that they should upgrade to) and on upgrading the working copies.
Combined with the fact that some software of the user depends upon
SVNKit for their svn support, and SVNKit's release was lagging behind
for 1.7.

But I'm trying to state the problem more generally: most users have
different clients, and those can have different release cycles. For
whatever reason. I think it's naive to ignore that problem.

Okay, maybe I can. But it's hard, especially because I'm not a
sysadmin myself on that system, can't build from source, so I have to
depend on installable third-party packages (Solaris packages in this
case). But okay, maybe this is going a bit in too much detail about my
particular situation ... don't want to bring in my organizational
problems into the equation :-) ...

But on Windows, I could just zip some svnclient from another system,
and unzip it into C:\Temp or whatever, and test whatever I want.
