This is a suggestion without code/patch to back it up, so my voice
counts for very little, but ...

Perhaps a trade-off which avoids offering unusable completions to older
systems is to code for two modes: "ssh -Q supported" and "ssh -Q not
supported" and to _only_ statically configure in zsh's completion those
completion values which existed _before_ "ssh -Q" was added.  This
provides a finite bound to data-value churn in zsh's completion.
