Greetings!

I would like to know about the VT plans. Historically, keymap
implementations are similar in the kernel and kbd project. I rewrote
it in kbd. So, it can handle keycodes bigger than 255. In a kernel
everything remained as before. I want to fix this part in a kernel. As
pluses will be:

* opportunity to define keycode > 255.
* opportunity to reduce this table a kernel in most cases.

I would like to ask your opinion about my plans because I heard about
the thought of moving this functionality to user space.

Whether it is worth starting so large-scale changes?

What I don't think we want to do is to make the current VT
implementation in the kernel significantly bigger.  That is why
proposals to introduce bidirectionality or character shaping generally
have not been accepted.  If you can improve functionality with a
*smaller* footprint, which you seem to imply above, then please, go ahead.
