There are, to my knowledge, no behaviors in NetBSD's TCP which will cause
it to not interoperate with any other TCP implementation (unless, of course,
that other TCP has serious bugs which cause it to have interoperability
problems, but I think that goes without saying).

Thank you, Erik, for putting this so well.  I happens to be my position,
as well.
