Good point, got confused :/

Keep in mind I'm also not a font guru.

$ fc-list Inconsolata -f '%{weight} %{style}\n'
100 Medium

So Inconsolata _only_ has Medium on my system (this is Inconsolata
001.010-6 from the debian unstable package). I assume the other weights
are synthesized via freetype in this case.

For comparison:

$ fc-list 'Noto Sans' -f '%{weight} %{style}\n' | sort -n
80 Italic
80 Regular
200 Bold
200 Bold Italic

So the weight mapping in Iosevka seems at least superficially correct.
Note that Iosevka is a open font, just in case you want to test this:

The version I've been using for these tests:

https://github.com/be5invis/Iosevka/releases/download/v11.2.0/super-ttc-iosevka-11.2.0.zip

it's a massive font due to all the style/weight combinations.
