If you can't help but split the edges, you can't help it. Generally though I've found that I can keep bevels together with their "parent" faces. Sometimes you can't. I honestly just try to keep the islands as intact as possible. So for example, the wing of a plane, I'd do my best to keep it all one, and only separating out the bottom. I really don't know if that makes sense. UV's are hard to really put into words. Pic related, the selected edges will bevel nicely when baked.
Again, sometimes you can't help but split up the edges, so I do my best to have them somewhere they're least likely to be seen. So if people won't see the bottom of your plane, I'd put them there.
There's not any guarantee that they'll come out bad either, it's mainly just a precaution more than anything.
But if people are going to scrutinize it all around, I'd start looking into UDIMs.
I don't know if any of that helps, because I might have misunderstood, so my bad if I did.
