I'm not convinced that a feature like this is going to get anywhere
near the level of real-world use case testing that it should have if
we don't actually use it. The only cases of new features that
absolutely require server side support that we've added since 1.0 that
I can think of are locking, ra_replay, and this. For locking sticking
it on svn.c.n would not have actually resulted in any real-world
testing. For replay the feature was sufficiently constrained that I
think it was simple enough to say "yep, this satisfies the use case"
without a bunch of real-world testing. With merge tracking I really
do think that the feature could seriously benefit from actual users
using it before we actually say "yep, it's done", even if just so we
can prove to ourselves that the user interface makes sense. I think
that a period where we eat our own dogfood would result in a more
useful feature in the end, and I think it's relatively low risk. Yes,
it's true that real-world tests on svn.c.n don't span the entire range
of use cases, but they do cover at least a subset of them, and I think
there's some benefit to doing it.
