Unfortunately not, those pressure related functions need a [libinput_tablet_tool](https://wayland.freedesktop.org/libinput/doc/latest/api/structlibinput__tablet__tool.html) instead of a `libinput_device`, ~That said, I haven't tried brute casting..~ trying that...

Doing the math ourself is also possible ...

I've discarded the self-made version. Much better like this, but still needs above `wlroots` patch. ~Note to self to post this patch in the wlroots repo.~

I've finally created a `wlroots` issue: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/4012
