yes, indeed, it doesnt show up in the doc.

I'm quoting Fabian from bugzilla:
Fabian Grünbichler 2023-04-24 13:48:07 CEST
yeah, some parts of the machinery are already in place, e.g., it's
possible to define a "proxyto_callback" that gets called instead of
resolving proxyto straight via the parameter. AFAICT that is not used
anywhere though ;)
probably it would mean caching the vmlist in each http server worker to
avoid expensive queries, plus implementing filtering of the vmid list
for the requesting user/token since we'd not want to leak existence or
location of guests that the user doesn't have access to.
So, it seem that Fabian have same opinion than you.
I was doing a simply rewrite to keep it simple, but
I'll have a look at proxyto_callback.
(BTW, vmlist don't seem to be so slow, i'm around 10 extra ms. I don't
think it need to be cached. (it's still faster than doing 1
cluster/ressource api call to find the node + the final call).
