However such conflicts are not documented. One could have thought
that the options were merged instead of being ignored.

Unless this have changed uptream, under Debian, the evdev(4) synopsis
doesn't tell to grab the device:

SYNOPSIS
       Section "InputDevice"
         Identifier "devname"
         Driver "evdev"
         Option "Device"   "devpath"
         Option "Emulate3Buttons"     "True"
         Option "Emulate3Timeout"     "50"
         Option "GrabDevice"     "False"
         ...
       EndSection

The synopsis should probable mention the InputClass directive instead.
