No -- BCP38 only prescribes filtering outbound to ensure that no packets leave your network with IP source addresses 
which are not from within your legitimate allocation.

Is this an accurate thumbnail summary of BCP38 (ignoring for the moment

the issues of multi-home), or is there something I missed?

    The basic philosophy of BCP38 boils down to two axioms:

        Don't let the "bad stuff" into your router
        Don't let the "bad stuff" leave your router

    The original definition of "bad stuff" is limited to source-
    address grooming both inbound and outbound.  I've expanded on the
    original definition by including rule generation to control
    broadcast address abuse.
