I would, but I'd quite like to support pagination and field filtering 
which comes with 3 optional parameters and then if you add a couple more 
for actual querying, the permutations could get out of control very 
quickly! Is there anything simple that could be done so it could at 
least match /foo?* Then it would still be possible to use the 
requestContext request at: approach
