I don't think I agree with this.

As I understand it, operating without network buffering could lead to
strange behaviours by the domain when it fails over - violations of
network protocols by "the" VM.

The default should be to operate correctly, and if correct operation
is not supported the default should be to fail.  (Cf security.)
