You are welcome to file bugs in the freedesktop.org bugzilla
(Wayland/libinput) for the feature requests you have. Some of them may be
closed as wontfix, but I suspect there are others the case isn't clear-cut.

Oh, and if you do so, don't just go through the synaptics/evdev man pages
and file a bug for every option in there. I want clear use-cases that
justify each features you want us to add.

Cheers,
