Why not?

Highways (if you mean motorways) imply 'bicycle=no' so you can't use the
tag, according to the proposal.

True, and I agree, although it's possible to argue that almost all
instances of access tags are about the intersection of the law and
what's in the ground — the signs usually tell if something is different
from the "law defaults".

In this specific example, it could also be argued that this is encoding
what's on the ground since the "D4: påbjuden cykelbana" sign is saying
exactly that the cycleway is the mandatory way for cyclists and it's not
allowed to use the road (barring the exceptions). If the sign was not
there that wouldn't be the case. Is it that different from a max speed
sign or a "no parking", or "no heavy vehicles" sign?

I'm not necessarily arguing here that all roads should be changed, or
I'm going to do start doing that right now. I just wanted to know if
there's any consensus in the SE community about that because this was
discussed to death in the DE and NL mailing lists and they concluded
that "cycleway=use_sidepath" would be useful, there was a proposal and
it was approved and it became "official" — so my original question is if
Sweden is one of the countries with the so called "compulsory
cycleways"? If no, in what way is Sweden different than Germany or
Netherlands? If yes, what do people here think about the approved proposal?

Personally, I do think the proposal is useful and if people are
interested I can further explain my reasoning. However, I would have
preferred if there was an official way of creating a relation between
the cycleway and the road, so the same information could be inferred by
having a road related to a path tagged as "bicycle=designated" (default
for cycleways). That would not require an extra tag and in case the law
changes only the inference needs to change, not the tagging.
Unfortunately that was not the approach that was approved; they seemed
to have chosen a more pragmatic one.

By the way, why is Sweden not listed here?
https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions

Did nobody care or is there no local consensus about what the default
is? It would help foreign mappers such as myself if the information was
there (I could not find it even in the Swedish pages). I would edit the
wiki myself if I knew what they are.
