When shopping for a new dimmer to replace a rheostat model, make sure
to specify an electronic dimmer.

I would challenge you to find one (for residential use) that ISN'T an
electronic (triac) dimmer! They've been that way for decades.

The only dimmers that aren't are the variac (variable transformer) dimmers
which are very large affairs which I've never seen in residential use.
They are, BTW, superior in terms of putting out a normal AC waveform, not
the weird stuff a triac dimmer puts out. As for a rheostatic (resistance)
dimmer, I've never seen one outside of an old theatre stage lighting board.

You beat me to the punch. I was going to say the same. Except for
maybe wacko millionaires, I don't think anyone had dimmers in their
home until they had transistorized** dimmers. Others were too big to
fit in the regular box, and too expensive too.. **I count any
semiconductor as a transistor, including triacs and diodes
