I don't understand this concern. Vacuum relays have been widely used for
decades for antenna switching in power amps, where the impedance, and
thus voltage and current, are the same as for this application.
What am I missing?

I would not use a vacuum relay in a matching network for a 1/4 w.
antenna. That's a low v. high current setup calling for open frame
contactors or at least large open relays. Perhaps this information
will render your question moot.
