It'd be fine by me; I don't know about Trond.

NFSv4 seems harder; in theory it's very extensible, but in practice I'm
not sure how you'd make a private extension without risk of colliding
with a later standard.  And you could update the SGI protocol for v4 and
use a separate program as with v2/v3, but the lack of sideband protocols
has been one of the requirements for v4....
