A good SSD will live forever in a low-usage environment. The biggest problem with flash devices in my experience seem like some kind of controller or component failure, not a write durability issue. Hopefully, a well engineered device with good components can avoid this type of failure. That's what we're all hoping because this is what everyone buys now... > Softdep is probably a good thing.

Swap is probably never going to be used.
