Feature request: settings map identical?

[AlexKnauth]

Either provide a function to tell whether two settings maps are identical, or guarantee that the integer handles are equal whenever the maps are identical.

I don't expect this "identical" operation to be used for implementing the Eq trait == on the auto-splitter side. My intended use case would be to allow a load_if_changed function on the auto-splitter side.

For example:
I load the settings map and call it A, and then load it again on a future tick and call it B.
If the settings map has been unchanged for that time, then either A and B should be different handle integers but which "identical" returns true for, or they should be guaranteed to be the same handle integer, in which case there would be no need for a special "identical" function.

Complication: if "the settings map" has been unchanged, but A has been changed by the auto-splitter, it would be wrong for the 2nd load B to have the same handle integer as A.

Related complication: if an auto-splitter loads A, then loads B which is unchanged, and then mutates A. They would not expect B to be changed.

So maybe making the integer handles equal is a bad idea, and an "identical" function is needed after all.
