Porting framebuffer+libevdev (Linux) to framebuffer+libinput (OpenBSD)

Greetings,

I am looking at getting a framebuffer back end for the OpenSmalltalk
IDEs up on OpenBSD.

So my question is "Is this a sensible thing to attempt?".

I am an old (read slow) guy who writes a small amount of C code about
once a decade and don't have a lot of resources to apply, but I do have
some persistence and can learn, sometimes.

My ol' brain does not do grand plan projects anymore, but is OK with
small projects + tinkering to success.

I updated a port of OpenSmalltalkVM's fbdev back end to Linux a while
back [tested on {Alpine,Armbian} Linux].

So my question is really to the libinput/framebuffer folks.

Is this something I should get into, or is it too large for my ol'
shrinking brain?

Thanks in advance for any input.
