The question is about paint primers. Don't let facts interfere.

I don't believe in painting over primed plaster. After 30+ years as a
plasterer, I avoid priming plaster walls, both interior and exterior. A
bit of work and you avoid old paint lifting after priming.

Good for you. Primers do help and paint adheres and looked just
wonderful. I'd even prime a 90 year old pastier wall.
Would you save the plaster?

It depends on the existing paint, oil or water based, most new paints
are water based, you need a primer if switching between the two. I like
Fresh Start primer.
