A seven speed bike will probably work on a modern direct drive trainer.

Sorta correct. A modern 7 speed cassette might physically attach on the trainer’s freehub body, but it’s not going to shift well on SteveK’s vintage 6 speed drivetrain. It’s apples vs oranges.

Your suggestion would be apples to apples for someone who has a 7 speed drivetrain on a bike manufactured in the past 10 years, though.

That is correct. I was however responding to your statement that “today’s direct-drive trainers will not work with bikes with less than 8 speeds on the cassette,” to add the information that today’s direct-drive trainers will work with bikes with 7 speeds on the cassette.
