Bug Description
The evdev protocol does not allow for retrieving the EV_SYN event codes. Instead, it uses the slot for the EV_SYN event codes for retrieving the event types supported by the device. The uinput driver also does not offer the ability to set EV_SYN event codes.
Thus, the "B: 00" event mask line is incorrect in format. It does not describe the EV_SYN mask. This will confuse people who try to read or manipulate evemu property files.

The EV_SYN events are not dynamic in the kernel. The evemu code reflects the data actually available in the kernel, which includes the event mask.
Changing a file format to reflect an arbitrary view of a mostly undocumented file format, a format which foremost is there to transfer data from the kernel to the tester via bug reports etc, is not a valid change.
Keeping stability is deems much more important, so I am marking this bug as won't fix.
