I also think this is a good addition to JavaFX CSS.

1. what are the plans / commitments for actually developing the dark mode
stylesheet?
I'm thinking a bit bigger than just "Modena Dark". Since JFX 19, we've
added focusVisible, platform preferences, CSS transitions, and now
hopefully media queries. After this is done, I think we should
leverage all of those new features, and create a bold new theme for
JavaFX that feels at home in the year 2025.
Depending on the scope, that's a pretty ambitious goal. :) Were you
thinking of something derived from Modena (e.g., a "Modena 2025") that
incorporates all of those things and maybe a few other tweaks? Or are
you thinking a brand new "from scratch" theme? Based on past experience
(the switch from Caspian to Modena in FX 8), the latter will require
quite a lot of work, and someone with a good artistic eye and attention
to detail to drive it. I expect it would be a fairly long process and
require a *lot* of testing.
Anyway, that doesn't need to slow down this feature. This feature would
help with either approach. And application developers would be able to
take advantage in their own stylesheets before that.
2. are there plans / necessity of adding more similar properties to the Scene?
Yes, where it makes sense. I think it should also have
persistentScrollBars / prefers-persistent-scrollbars.
Yes, this would be useful.
After that, we're probably good for a while.
Sounds good.

3. are there plans to provide a similar proposal for variables, for example to
be able to size controls consistently
https://bugs.openjdk.org/browse/JDK-8314683 ?
Yes, although this requires a new CSS parser.
Have a look at this proposal, specifically the "Variable substitution"
section: https://gist.github.com/mstr2/f416996caf48e11193f0b6a5883a3926
Variable substitution requires a value resolution algorithm that works
on the level of CSS tokens, not on pre-parsed objects.
One more tangentially related question: do you think it's possible to be able
to determine which selector in which stylesheet was used, for debugging
purposes? For example, be able to enable logging?
Interesting question. I don't have an answer (or a guess) at the
moment, but I'll think about it.
