Yes, I did. . . . . . After the fact.😁😁
I had it strike from within in one of my amplifiers a couple of months
ago. A failed vacuum relay in the output resulted in the loading wafer
of the bandswitch getting a direct hit of 'lightning from within."
Luckily I was able to get a spare wafer. The replacement process is not
going to be much fun.

And specifically lightning causing issues.
So there's that...
Did you see the smiley face at the end of my statement? Perhaps not....

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.
