It happened on my Martin. I let it be until the whole section came off. Eventually the guitar was without binding. It sounded the same to me. Then I took it to the guy and he had it reglued. I think it was a couple hundred.
Generally you can just have it reglued assuming the binding is still otherwise stable. How vintage are we talking? It's not uncommon for some types of binding to deteriorate to the point it will come off in pieces. At that point someone who knows what they're doing can patch it. I would get it fixed before that happens though.

Leave it, battle scars are cool.

I was told 1950s -- it was twisting and almost ready to crumble & I know that material (including pickguards) dissolves over decades.
