Actually, many countries do not have something like a "state equivalent",
it is a particularity of the USA because they are a federal republic.

I was not going to get into discussion about cities and other lower level
admin entities. Please lets stick to the state question.

yes, this is also something I wanted to point to, because in the discussion
for this style change it was argued that some countries, which currently do
use level 3, should change that to level 4 (like the US), and I was arguing
the other way round, that the US should probably change the states to level

It appears to set a minimum size of 750 "way pixels" at z4 and 3,000 at z5

I am not sure why raising the importance would lead to less names
displayed. If this holds true, the stylesheet would have to adopt to
correct this IMHO.
