Noone would be hurt. Say you have user with the address
fred-foobar@???. You don't know that the addess is non-VERP
and thus strip -foobar and treat the user as being fred@???.
As you see, nothing scary happens (except that messages from
fred-spammer@ and fred-gangster@ and other nasty Freds from
@galaxy.universe will be accepted, but that's not a very big problem
anyway, is it?).

My concern is that messages from mailing lists I subscribe to arrive
without a delay caused by greylisting. The suggested workaround works
in that case.

Note that "+" is also frequently used in VERP addresses.
