It is the same type of concept. Typestate, effect system,

If I remember correctly Rust *did* have a typestate system very
early on but it was done away with in favour of the borrow
checker.
Yeah, I've seen the Rust creator write about how they started out
with all whistles and bells with the intent of having a full blow
effect system. Then realized that they had to make things simpler
and focus on memory management because that was the most critical
feature. Probably a wise strategy to go for simplicity and hit
version 1.0 sooner.
Having a simple core language is usually a good idea. I see now
in the rust forums that people use the borrow checker for other
things than memory, like tracking what thread you are in:
