I do not know which sample you take your observations from. Since
NETCONF well predates YANG, it did not mandate YANG and hence data
models specified in say XSD are not a surprise. What is broken is the
notion of <tag>lots of proprietary unstructured cli</tag> and your
text was somehow hinting at this being the state of that art.

Your sentence did make it sound like a format conversion exercise,
which I have to object to. The NETMOD working group, in particular, is
not "converting many MIB modules into YANG format to provide core data
models".

So then give it time and please do not draw a picture about NETCONF
and YANG which I think is not fair.

Thanks.
