This is interesting - there seems to be some confusion. Maybe you can
help me.

Well, you wrote, and I quote:

There are plenty of older houses around here with old
wiring, old fixtures, and old dimmers.

As you noted, our experiences differ: I've *never* seen an old (i.e.,
non-triac) dimmer in a house with old wiring and old fixtures. And I've
worked on plenty such houses (in the SF Bay Area). Maybe it's a
geographical difference.
