Because SMIv2 (RFC 2578) defines MIB objects with a *maximum* level
of access (rather than an exact access), and has increased the number
of possible access values.
   Allowing arbitrary combinations would have introduce an unnecessary
level of complexity.   "read-write" effectively covers "write-only" anyway.

"write-only" is not a valid MAX-ACCESS level in SMIv2, so has been
deprecated in the conformance definitions as well.

If you need a more official answer, you should ask on the relevant IETF
lists.   This list is really intended for support of the Net-SNMP software.
