[db-wg] Restricting WHOIS searches to type: netname

One of the helpful options provided by the RIPE WHOIS server is the
--types option which provides a list of what specific object types
a given set of query results may be restricted to.

That list is as follows:

inetnum
inet6num
as-block
aut-num
as-set
route
route6
route-set
inet-rtr
filter-set
peering-set
rtr-set
domain
poetic-form
poem
mntner
irt
key-cert
organisation
role
person

Can anyone explain to me why "netname" is not on the above list?

I would like to be able to query the data base for "ABC" but restrict
the query so that I only get back the records for the dozen or so
IP blocks whose registrants have (unwisely?) elected to label their
networks as "ABC", while NOT also getting back all 16 or so of the
organisation objects whose org-name: field contains the substring "ABC",
much less the numerous and additional person and role records whose
person: and role: fields also and likewise contain the substring "ABC".

If I can selectively query just for poems, is there some reason why
netnames deserve less respect?

And as long as we are on the subject, may I safely infer from the
presence, in the data base, of a dozen different networks named "ABC"
that no attempt has ever been made to insure uniqueness of netnames
within the data base?  Are netnames even restricted, as they seem to be,
to having a form which is rather strikingly reminicent of actual unique
data base handles, i.e. consisting of only alphanumerics and hyphens?

P.S.  I do not mean to pick on RIPE specifically here.  A quick check
reveals that whois.apnic.net and whois.afrinic.net also fail to support
selective querying for just netnames... although in those two cases
selective quering for poems is also not an option... a sad fact that
has left me rather entirely bereft, as I'm sure you can all imagine.
