I'm grepping the patches and cannot find any snippet that decides
whether to use 24-bit escape sequences or zsh/nearcolor module. How
it's decided?

You've also written: "No true colour escapes will ever be generated if
you don't specify colours as hex triples anyway. And even if they are,
they should be ignored.".This sounds like: if true-color/near-color
was not enabled, ignore hex-triplet. But I think there is no switch
(e.g. an option) to enable true-color support?
