Having proper and consistent Multitouch support on all platforms is
certainly
an interesting goal, especially if your development is targeting a
mobile platform. If one
could test the input behavior already on the desktop, this would be an
enormous time saver because the turn-around times
(edit-compile-build-deploy-debug-curse)
for mobile are currently still extremely high and thus not very
development-friendly.
I learned from your mail that the situation on Windows seems to be better
than on macOS, which is my current development environment. That gives
me an idea :-)

Nobody is biting... so is anyone else out there interested in using HID
touchscreens with JavaFX on OSX (or any other plaform) without using a
third party driver?

Multitouch display support JavaFX on Windows, iOS, and Android seems
straightforward. If the OS recognizes the display as multitouch, then the
chances are that JavaFX will also work with it since it relies on the
native multitouch support of the OS.
When it comes to Linux and OSX, it's not always as easy. Linux sometimes
requires device mapping. I'm not sure if it works at all in OSX unless you
have specific drivers for the display.
All of the platforms seem to support HID so maybe JavaFX could have direct
support for HID devices (optionally) if they are present instead of just
the current method. It may also improve performance in cases where the OS
is just piping HID events through their own API's to support multitouch.
Why not just go straight to the HID source and bypass that conduit.
This would vastly improve multitouch app development on OSX. It would be
possible to connect a HID display and use it for testing apps that are
destined for platforms that formally support multitouch.
Is there any work being done in this area? Is there a bigger picture
(e.g. better multi-display and connect/disconnect support in JavaFX)?

easy JavaFX support.
