Yes you missed my point. Users don't care why something is
broken, just that it is and that they now have to perform some
manual operation to get it to work again. Score a -1 for svn user
happiness. No reason to punish an user for something that is
most likely outside of their control.

True, but it is there for the exact reason we are arguing about :)
(That clients which ignore this advice will not work correctly
in a lot of real-world situations.)

I completely agree this is the preferred solution.
(Sorry for being so persistent about this. Just a pretty big sore
spot at the moment because I've been implementing a subversion aware
proxy. To be honest neon has been very easy to work with. Serf
has been nothing but problematic. Old Serf versions were very
easy to crash and get into infinite loops especially when dealing with
proxy authentication. I feel bad I didn't have time to look into
the problems until recently, especially since you are usually so quick
to fix them - all problems I found were already fixed in later Serf
versions than I was testing. I look forward to the latest 1.2.2 Serf
changes since I think it should finally be stable enough to be supported
in my expected non-utopia situations.)
