well, you might end up sending the message in the clear. Whether
that's better or worse than RC4 depends on the perception of
both the sender and the receiver. However, if they desparately
care, they might encrypt end2end.

The RFC first and foremost gives _implementations_ (libs and apps)
a hook to cease supporting RC4, so depending on sw vendors and
maintainers (and your sw update cycle), you might not have these 2-3 years.
