[c-nsp] Pros/Cons to *disabling* mac-address aging-time <> "routed-mac"

[Randy]

I have inherited a setup:
 - cat6509E's running IOS: various flavors for SXF. In the process of upgrading to a standard-flavor of SXI4a.

I see that all 650x have mac-address-table aging-time <> "routed-mac" enabled by default.
There is a fair amount of inter-SVI communication that happens but it is within the same switch.

I am thinking:

Turning-off(mac-address aging-time 0 routed-mac) can only help but won't hurt!

Any thoughts/experiences wrt to above would be appreciated.
Thanks,
