Understandably so. I've been trying to leave breadcrumbs and beg for
help over the past several months, but nobody has taken me up on it.
I've been hacking around on Ev2 as I can, but Real Life is leaving
little time for that these days. I can consult, direct and review,
but my hacking time is very limited.

We can always shuffle headers around or document the things as
experimental, so committing ourselves to the API as this point isn't
my concern. The only real limiting around Ev2 and 1.8 is issue #4116
which is svnrdump failures over ra_serf. In the issue, I propose
using Ev2 to get around the problem, since the dumpfile format is so
incongruent with the editor.

Of course, we don't *have* to do that, but as I've thought about it,
any solution will require a bit o' caching---which we've already
implemented as part of the Ev2 shims. We *might* be able to implement
the svnrdump editor as Ev2, shim the thing on the client side (which
gives us the required caching) and release that way. Or there might
be a better solution I'm overlooking because I've got Ev2 on the

+1, and I'm sorry I can't help more.
