I am curious about your statement. You say "insert a (lossy) capacitive
reactance in series". Why would a braidless piece of coax inserted in a
tube have significantly different loss than the intact coax of that length?

I've made matches made that way for decades that ran at full or near
full legal limit on 6m. I'm pretty sure that any significant loss would
have shown up as dripping plastic. The matches when taken apart after
years of use show no sign of heating.
