This is a bit like asking "who still uses keyboard shortcuts?"
After all, there is really no reason that anyone using Paint in Windows would ever type Alt+F and then A when they want to do a Save As...
Right? Sure, it worked for the last 30 years. But come on, who ever would type Alt+F and A? It has to be less than 1% of all the Windows users out there. And our telemetry proves it!
If you have a billion Windows users, and you rewrite Paint - as Microsoft did in Windows 11 - so it no longer knows the keyboard shortcuts that 1% of your users rely on, no big deal. You've only inconvenienced ten million of your users.
Or you hit Alt+F4 on Paint and you have an unsaved image. There is a nice dialog that asks "Do you want to save your work?" And there is a really common case where you were just using Paint as a scratchpad and you would like to type Alt+N here to say "no worries, I was just fooling around."
This dialog used to read "Yes | No | Cancel". And Alt+N let you say "No".
In later days, the dialog changed to "Yes | Don't save | Cancel". But with a clever trick, Microsoft made the "n" in "Don't save" the shortcut key. So even with the updated and much more clear wording, your Alt+N still worked!
Until Windows 11, where this code was all rewritten by people who never knew that anyone ever used these keyboard shortcuts.
The TrackPoint may be something like this. Those of us who insist on it may be small in number. But if it is ever removed, then the one reason why we will only buy ThinkPads is gone. We may as well get a Dell or an HP or a Mac M1 or whatever.
