I think there are differences between the two that make this awkward.
Does anyone actually use alternative data stream for anything that makes

Somebody would have to make a convincing argument that it's worthwhile.
Note there's also a proposal to add extended attributes to the NFSv4

That also has some more discussion of mismatches between the named- and
extended- attribute interfaces:
