We agree on this, I have no opposition to NTFS checking size of files
used to store EAs and rejecting any write more than 64k

Inheriting stat data from the parent directory should be a feature
available not just for streams, but for all files that want it.
Efficient small file access to a 32 byte file should be a feature
available to all files, not just EAs. Not being listed in readdir
should be a feature available to all files, not just EAs. Constraining
what is written to them should be a feature available to all files, not
just EAs, and arbitrary plugin based constraints should be possible.
Is this more clear?
