This project provides binaries without any link to Rust or Cargo. It is
just normal binaries that appears to be written in Rust. Therefore, it
does not makes any sense to distribute them in a Rust-specific registry.
Furthermore, such publication would not include the man pages
installation may not respect some distribution-specific policies.
As discussed in #2, ring is not mature enough to replace OpenSSL. Hence,
the standalone mode which has been made to implement such a replacement
has to be removed until ring becomes usable.
ACMEd should and will remain as simple as possible and let the user
alone take care of the challenge validation. However, this philosophy
does not forbid the project itself to distribute additional tools that
are designed to improve the user experience. Because the TLS-ALPN
ecosystem is currently very slim, adding tacd is really benefic to
ACMEd.
