Nit: I probably should have done this, but mind grouping this into sections and
commenting? i.e.

# Legacy IPC
'*_messages.cc',
'*_messages*.h',
...
# Mojo IPC
'*.mojom',
...
# Android <something>
'*.aidl',

       # Blink uses a different file naming convention
       '*StructTraits*.*',
       '*TypeConverter*.*',
   ]
 
   # These third_party directories do not contain IPCs, but contain files
   # matching the above patterns, which trigger false positives.
