Thanks. I guess since I installed it fully before finding this out, I was looking for if was a silly worry to have or not before starting again with another distro.
I suppose I'll just let it stew in my noggin before deciding if the slight extra peace of mind is worth it, even though I have disabled auto updates with their hacky (unsupported) method of marking my connection as metered (who knows if thats reliable since its unsupported).
