Amen to all that.

When a 1.5 client has no requested depth, does it still transmit
recurse=yes in those RA layers that today transmit recurse=yes by
default?

Say "Other requested depths are honored by the server properly..."
^^^^^^^^^
...just to be clear :-).
This whole last paragraph looks correct to me, but the meaning of the
first sentence might be clearer if expanded to this:
"When a 1.5 server receives both requested depth and recurse, the
recurse is ignored in favor of the depth, even when the depth is
svn_depth_unknown. But when a 1.5 server receives recurse with no
requested depth, it honors the recurse, on the theory that it's
talking to a pre-1.5 client."
(You've sort of organized your text around the client version, but we
really need to talk about server behavior in detail for the reader to
fully grok what's going on, IMHO.)
