Well, you don't want to directly encrypt data with RSA either, for
end-to-end data encryption, CMS (or PGP, ...) is the appropriate
high-level tool.  And with CMS one needs to carefully consider whether
to Encrypt-then-Sign or Sign-then-Encrypt.

The fact that RSA directly supports encryption of data up to the modulus
size is often more a curse than a blessing.
