Public bug reported: The trackpad on T2 Macs needs to increase its AttrPalmSizeThreshold in libinput quirks to 1600 in order to have proper palm rejection. The current value of 800 results in normal finger taps being rejected and the trackpad being aggressive in terms of palm rejection.
Fortunately, this issue has already been fixed in upstream libinput here: https://gitlab.freedesktop.org/libinput/libinput/-/commit/ed9570df6065d2f29e0ef7946505f90167588906 I've also attached that patch with this report.
