I have a question out of curiosity… Is it supportive in a good way or do the ab and back muscles start to weaken with time if you don’t make an effort to strengthen them?

They’re supportive like a back brace. Modern back brace construction borrows quite a bit from corseting.
If you wore them too tightly for prolonged periods because you were an actress or socialite, your core muscles may weaken eventually because the corset did all the posture work, sure.
That was a thing, but pretty rare since average women wouldn’t tighten to impractical amounts.
