Hi,

Indeed.  I’ve just realized that commit
f9c62b23cc88541756656b3ec602ce987828d906, which added that deprecation
warning, will actually only fire with daemons dating back from before
2018 (the date at which ‘PROTOCOL_VERSION’ was last updated in
‘worker-protocol.hh’).  Going back to this issue at hand, it won’t
report a daemon that lacks lzip support.

Mathieu, Maxim: I think we need a finer-grain mechanism here, or maybe a
new builtin that would let a client ask the daemon for supported
features.

Thoughts?

Ludo’.
