(Get the code!)
Logging into Ubuntu (i.e., not "Ubuntu on Xorg"), the "Disable While Typing" Touchpad setting in gnome-tweak-tool now appears to work. Furthermore, tapping to click does _not_ work, i.e., the behavior I want is present by default as far as I can tell. In fact, I can't figure out any way to cause tapping the touchpad to generate a click. So either the behavior has changed in an update since I reported this bug, or I was using Xorg but thought I was using Wayland.
Logging into Ubuntu on Xorg, without anything special in any of my X server config files, the "Disable While Typing" setting in gnome-tweak-tool doesn't do anything, and tap to click is enabled and there's no way I can find to disable it. So that appears to be a bug in GNOME, not a bug in libinput. There should be a way to disable tap to click, and the "Disable While Typing" setting should be obeyed. If it's not, then I believe that means GNOME isn't populating that setting through to the X server the way it needs to be, which doesn't sound like a libinput bug.
Logging into Ubuntu on Xorg, these lines added to the "libinput touchpad catchall" section of /usr/share/
Option "Tapping" "false"
Option "DisableWhileTy
Option "PalmDetection" "true"
Perhaps this is a libinput bug, or perhaps the synaptics sections that are being applied to the device after the libinput sections are overriding the libinput settings?
Again logging into Ubuntu on Xorg, if I add this to my X config then tap to click is gone and it seems like there is _some_ protection against brushing against the trackpad, although there still isn't full disable by typing:
Section "InputClass"
Identifier "disable touchpad tap to click, enable palm detection"
Driver "synaptics"
MatchIsTo
MatchDevi
Option "MaxTapTime" "0"
Option "PalmDetect" "on"
EndSection
So, the potential issues that _I_ see here are that the Disable While Typing setting does not work in "Ubuntu on Xorg", and that the libinput options I'm configuring into my X server don't appear to take effect. Should I indeed open a libinput bug about that, or re-open the bug I opened and closed but clarify in the re-opened bug that it only applies to Xorg, not to Wayland?
