It is more a matter of opinion, but I once noticed the following with
`smime.el'.

  - `call-process' / `call-process-region' (temporary files in /tmp/?)
  - environment variable(s) for password passing
  - documentation encourages use of un-passworded .pem
  - password caching via elisp instead of external agent
    - personally avoid, even for tramp + SSH
  - the very manual .pem key/crt setup was tricky

Some of them you mention in the comments. EasyPG mentions some of them
in its comments/docs wrt other Emacs cryptography libraries. Not a big
deal, perhaps.
