Community members such as Gerrit Grunwald have already demonstrated an
application with a single JavaFX code base running on Windows, MacOS,
Linux, Android, iOS and even Raspberry Pi.

BTW, I totally disagree with you on your comments about the similarities of
the desktop UIs and some sort of unique, device-specific UI on mobiles and
tablets.  The truth is, the desktop OS UIs are vastly more sophisticated
than phone or tablet UIs and much harder to make look good in a
cross-platform way.  By contrast, there is usually very little to the
actual "native" look and feel of iOS or Android and skinning a JavaFX app
and supporting touch/gesture interfaces etc. is comparatively much easier.

I think it's fair to say that (random) iOS apps 1 & 2 will typically look
more different from each other than Windows apps 1 & 2.

There is no point in focusing exclusively on a desktop solution as the
majority of *new* app/application development is occurring in mobile and
embedded space.  It's true that there are several classes of application
that will *always* require a desktop OS but we must move forward and ensure
that JavaFX apps achieve a separation score of zero when evaluated against
my "6 Degrees of Separation" defined here:

To me, JavaFX is the Holy Grail we have been looking for... or at least it
*will* be when the iOS and Android ports are kicking arse.  And I have
*every* confidence in those fine people looking after those ports that they
can do just that.
