Path rule limit in URL Map for GLB

[amitgarg]

We have a requirement to route different URLs from GLB to different apigeex instances based on some path patterns.

For this , We have identified that external GLB has the capabilities to route the request from GLB to apigeex using path rules in URL maps.

But it seems , there is a limit ( 1000 for classic extenal GLB & 50 for external GLB) of path rules or route rules in external GLB as per google cloud documentation.

Questions - 

1. Is the above limit for path rules in external GLB ( for both classic & new one)  is soft limit ot hard limit ? What is the actual soft limit & hard limit for URL maps count in GLB?

2. Can we ask google to enchance the path rules and URL map limit per GLB as per our requirement ?

3. If yes for question 2 , What would be the highest limit we can have for path rules and url maps per external GLB ?
