There is no "bare minimum". Either you implement the "BIP" fully or not.
There is no inbetween. Likewise, the standard cannot be extended unless
you create a new standard that is based on the old (without re-using the
path, of course).
We're lightyears away from a BIP. Lets first create implementations and
see if they are compatible in all possible combinations and situations.
The moment any two apps have a different view on their wallets generated
from the same seed, they're incompatible. In this case they should
either fix the issue or intentionally choose incompatible paths, so that
they don't see and spend "subsets" of each other.
