I would note that RFC 7368 says that "simple Layer 3 topologies
involving as few subnets as possible are preferred in home networks". I
presume this is reflective of WG agreement.
While it does go on to note that multiple subnets are sometimes needed,
mandating that each physical port on the access router be a distinct
subnet (much less extending such a mandate further in the home) seems to
violate this agreement.

Sure, ISIS could be made smarter when it comes to this, but it all comes down
to what the requirements are. Right now when we started to evaluate routing

even what a homenet looks like.
I think it is you who are not on the same page, not the working group. The
working group recently published a document describing our goals, RFC 7368.
Many of the points you have raised as supposed points of disagreement are
addressed in the document, although I will admit that it is not always obvious
that they have been addressed. The case of routing over Wifi was discussed at
length; the text referring to it in the document is here:
Due to the use of a variety of diverse underlying link technologies,
path selection in a homenet may benefit from being more refined than
minimising hop count.
Regarding your criticism about people pitching their favorite routing
protocols, you seem to be doing precisely that, so the criticism seems a bit
unfair. The responses you have been hearing seem like legitimate attempts to
address points you have raised on a technical level, not mere advocacy, and it
is unfortunate that you would suggest otherwise: I haven't actually seen you
raise any technical points in favor of IS-IS, which you seem to be advocating.
