Yes, it makes perfect sense. I'd still probably do
$final_banned_destiny = D_DISCARD;
$warnbannedsender=1;

Yes, it is not advisable because 90% of the banned messages are viruses
for which you don't have a signature yet, or spam. And the source
address is probably forged. So your box becomes a contributor to the
problem (backscatter).

If there were a way to only warn on messages that passed SPF, I'd think
about it again and might start adding some warnings in. But if
Amavisd-new has a hit on banned, that takes precedence over spam, so you
can't chunk the non-verified senders in the ash-heap...
