Lots of people have developed best practices on these topics.  The
problem is pushing against the business side and keeping these in
place, and not letting the bar be low at your upstream and peers.

There is a secondary issue that is yet still unaddressed.  Some vendors
still send all routes they receive out to all external peers in the
absence of a policy.  This is something I want to see corrected as it
will require a bit more intelligence when it comes to BGP policy to
provide the expected behavior.
