Although the `acme-lib` crate comes very handy when creating a simple
ACME client, a more advanced one may not want to use it. First of all,
`acme-lib` does not support all of the ACME specification, some very
interesting one are not implemented. Also, it does not store the account
public key, which does not allow to revoke certificates.
In addition to those two critical points, I would also add `acme-lib`
has some troubles with its own dependencies: it uses both `openssl` and
`ring`, which is redundant and contribute to inflate the size of the
binary. Some of the dependencies also makes an excessive use of logging:
even if logging is very useful, in some cases it really is too much and
debugging becomes a nightmare.
