Users wanting this new behavior could still use the ingress keyword even on egress interfaces?

Broadly speaking, that should indeed counter most of the negative effects you'd expect from disabling this tweak in egress mode.  But it doesn't really answer the question of whether there's a compelling *positive* reason to do so.  I want to see a use case that holds up.
