Feel free.

Presumably the names are tied to DDX rather than vendor, which could
easily make it either.  The worst they can do is to add non-colliding
keysyms.  There's no way they can add keysyms that conflict with what we
have now.

That's ... a lot of keysyms.  Could you not use modifiers for this?

Can you elaborate?  Do you have one row of function keys, and these are
essentially modifiers that shift the function number?

Can you elaborate on this?

XF86XK_Messenger.

Can you not use pointer keys to simulate a mouse button?

I assume this is yet another modifier.  Maybe take Hyper?

Dude, you can't add 200 keysyms for languages.

Could you not use XK_Mode_switch and have the language smarts in
userspace?
