But there is no lightning inside of an amplifier... Hopefully. :)

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.
