Cisco's configurations aren't rubber.  You can only stretch them so far.
Every exception is more stuff in configuration on a dozen of routers.
This also increases CPU load.

If you think Sprint's goal is to reduce table size you're wrong.  The
goal is to avoid routers going belly up from overload.  So the approach
is to have a blanket policy which is not too expensive to compute but
does contain growth _on average_.

PS. Here's line counts for you to appreciate better why Sprint engineering
    does not like exceptions:
