SVI 'ip helper-address' not parsed by 'sh run | sec int'

I noticed that for IOS and IOS-XE the 'ip helper-address' command is not parsed for a normal 'sh run all | section interface', but it is captured by the 'sh run nve' command.

It would be very nice if the logic for parsing 'ip helper-address' could be added to the 'show running-config all | sec {interface}' and 'show running-config interface' command outputs.
