All these commands are actually clients, they connect to the server and
request something.

You should be able to run these subcommands from the client, ie:
xpra stop ssh:HOST

Separating these CLI subcommands from the "real" GUI clients is planned:

Use:
/Applications/Xpra.app/Contents/MacOS/Xpra
There are a bunch of other executables there and also in:
/Applications/Xpra.app/Contents/MacOS/Helpers
(those are mostly for debugging purposes)

Opinions differ on that one:

I guess that's what an absolute minimal build would look like.

If you care about performance, you need to add lz4 and ideally at least
one video+csc codec, ie: vpx and csc.
And if you enable "client" then you really should enable "opengl" too.
The non-opengl client gets tested less and less with each release and as
the opengl drivers mature.

It's not clear to me what the "csc" flag does, as there are multiple csc
modules in xpra. The one you want to be using is "csc_libyuv".

> Is it worth me filling a bug with Gentoo, to suggest making lz4 a default? It seems to pull in only a single dependency, so hardly a burden.
Yes. lz4 is tiny yet it provides massive savings.

> I do appreciate the assistance you've given me, on this occasion and previously.
Thanks!
