As far as I know, there are no guarantees are the language level.
There are some (partially documented) implementation details

Yes there are - plenty of them :) The example I gave is a language
guarantee.
Would you point to the documentation location where this is guaranteed?
I lost track of which exact guarantee we're discussing here. In any
case, the documentation for the id() function ([1]) says:
"This is an integer which is guaranteed to be unique and constant for
this object during its lifetime. Two objects with non-overlapping
lifetimes may have the same id() value.
CPython implementation detail: This is the address of the object in memory."
Does that answer your doubts?
