So if I understand the whole picture correctly the situation has actually
nothing to do with directly working OSC in favor of python-*client provided
CLIs but actually moving everything to OSSDK so it can be supported and
used by OSC to be used as default client for everything? As that seems to
be a consensus that it's not enough to get the OSC to do the right thing if
the client lib under the hood is still python-*client and specially if
My question at this point is, do we (as a community) have enough bodies
dedicated to OSSDK _and_ OSC to make this sustainable? I'm being sincere
here as I have not been part of the development of either of those
projects. But if my assumption above is correct, I think we should talk
about these things with their real names rather than trying to mask this
being just OSC vs python-*client CLI thing.
