Yes agreed, but while I can't prove anything, it just worries me being
constantly one sided.

There are a couple of us intending to investigate the hf ac heating, so
we will see...

Course, you could circumvent all these worries by just heating a
plate of suitably-coated metal from outside the glass, with a big
****-off laser.

Just a BIT inefficient, but hey, you gotta pay to have the best!
