Yes, it's a fully non intrusive mod ; like all my mods.
The save files are corruption free, you can load them without problems even if you don't use the mod anymore. This while the mod itself is already compatible with any future updates that can be released. Sometimes a novelty will not be handled by the mod, but you'll not be deprived for it, nor for the mod.
At worse, there's a major change in the code, and the mod should automatically disable the related feature(s). What mean that not only the game will continue to works without problems, but you'll also continue to benefit from the other features of the mod.
I use "should" because I can have forgot a test for this, or for that. But so far this security measure worked anytime it had to apply ; for this game it was when Mr.C changed the User Interface.
You hurt my poor little heart, snirf
