The car sits there and purrs.
It takes longer now, but the oil light does come on after awhile. I was told by my indy, and others here, that the symptoms suggest bearing damage. Don't know what to make of it.

Yes it could be bearing damage.
But it could be something else as well.
I don't think you mentioned mileage????
Until you do a methodical evaluation-diagnosis and find the root cause your just guessing.
Even educated guesses from experienced mechanics are still guesses until proven right or wrong.
Do the simple things like pull the sump pan and see if there is excess wear particles present. Could indicate excess bearing wear.
Check the oil pump pickup screen. could be clogged.
Check the oil pressure relieve valve. it could be malfunctioning.
check the oil pressure sensor-sender and wiring. could be an issue there.
Assume nothing.
Prove or disprove the rest
