Fully support. Speaking as an operator, this is the right thing to do, and it has been deployed as a standard practice either natively if implementations do support this now or as an initial policy preconfiguration if it is not yet supported.

A small nit on the clarity of the applicability to al address families - the way how it is worded now seems to assume global and VPN address families only. What about explicitly requiring all address families active on the session to be affected by this?

OLD:
   This specification intends to improve this situation by requiring the
   explicit configuration of a BGP import and export policy for any
   External BGP (EBGP) session such as customers, peers, or
   confederation boundaries in a base router or VPN instances.

NEW:
   This specification intends to improve this situation by requiring the
   explicit configuration of a BGP import and export policy for any
   External BGP (EBGP) session such as customers, peers, or
   confederation boundaries for all enabled address families.

    Howdy WG folks,
    This request starts the WGLC for:
      <https://datatracker.ietf.org/doc/draft-ietf-grow-bgp-reject/
    <https://datatracker.ietf.org/doc/draft-ietf-grow-bgp-reject/>>

    with abstract:
      "This document defines the default behavior of a BGP speaker when
       there is no import or export policy associated with an External BGP
       session."

    please have a read-through, decide if this needs more work and
    then speak up on list.
    thanks!
