SNMPv2 will probably take another year to reach full standard status.
Some of the MIBs RREQ requires are not even at that level yet.  It is
going to take longer than that for the next version of RREQ to come out
(assuming another version follows this one).  Given these, I suggest
that mentioning SNMPv2 is reasonable, but conditionally, as in:

    "When SNMPv2 reaches Full Standard, you MUST implement it.  You MAY
    continue to implement SNMPv1 at that point, but you MUST not allow
    use of SNMPv1 to compromise the security constraints imposed by
    SNMPv2".

Unfortunately, some of the comments and rules in section 8.1.1 do not
apply properly to SNMPv2 and it is probably too early to make v2
specific rules up.  Example: routers need not implement the INFORM
operation.

I agree with the change.
