Hello,
The proposed iana-entity.yang seems to take the same approach: one file
defining 28 identities.
And I share all your concerns about iana-if-type.

If you design your models using identityref and define the
identities in separate modules e.g. compression-zip.yang,
compression-gzip.yang, etc. you can just chose not to load the

your device starts.
Right, and I have proposed this approach several times in the past.
However, some people prefer that the modules defining identities
mirror IANA and similar registries. In the case of
iana-interface-types it also means that implementations have to deal
with obsolete, obscure and experimental interface types that happen
to be in the IANA registry but nobody will ever want to use.

The 275 identities defined in iana-if-type.yang appearing as possible
/interfaces/interface/type tab completion options in a YANG aware cli
or drop-down menu in gui is annoying and stands out as an obvious
problem.
It is not late to split the file. No standard RFC YANG model includes
iana-if-type.yang yet. The actually referenced identities in current
drafts is less then 16 (grep-ing in my known YANG model archive)
{ethernetCsmacd, l2vlan, ieee8023adLag, ifPwType, pos, atm,
atmSubInterface, sonet, otnOtu, frameRelay, bridge,
macSecControlledIF, fastdsl}
If not single instance per file maybe dividing the file into
categories so if your device is atm aware you import
iana-if-type-atm.yang and get {atm, atmSubInterface}.
However we can probably agree the iana-if-type.yang exception is not a
valid excuse for new models like the one in the example where there
are 3 compression methods to not modularize the identity definitions
into separate files and not load identities the implementation does
not support but instead resolve to workaround solutions.
