I don't have a concrete answer, but adding the pattern explicitly is one

I have no problem with there being some naming scheme. I fully support
the idea of some set of rules that, given an explicit *pattern*, will
output a *name*. However what I see unfolding in this discussion is a
set of rules that, given a *name* will output a *pattern*, and that such
rules will be normative -- i.e. if your implementation doesn't parse
the name and construct the pattern, you're violating the spec. That
causes me distress.
*From the implementation's (e.g. cacophony's) point of view* it is my
intention to declare the handshake name to be an opaque value that is
set by the author of the pattern, with the library providing a set of
off-the-shelf (name, pattern) pairs so that hopefully the end-user will
rarely have to define their own. I think this design decision leads to
a far more simpler and more elegant implementation, and I would hate
for the spec to be defined in such a way where this behavior is
considered a violation.
