There is different degrees of frets, most are eventually fatal but some never go any farther.
One option you do have is to grind the belly flat and add a compression strong belly lam. I did this with great results on an osage recurve I made a few years ago.
If you don't want to go that route just shoot it and enjoy it as long as you can. Do keep an eye on the frets to be sure that aren't getting worse.
