Sorry, I’m not sure I can follow. Is this a bug in my Trackpoint
firmware and I need to update it?

Are you saying the sysfs settings are not supposed to work? From a
user’s perspective I’ve upgraded my kernel (to a stable version, into
which that patch was merged), found my mouse too fast and a knob called
“speed” in sysfs. Just touching that knob (by echoing the same value)
broke my mouse entirely, and that’s the problem I’m reporting.
I’m using i3 on “plain” Xorg, no Wayland or any desktop environment.
synclient only appears to have options for the touchpad, as far as I can
tell from the names:
