Aaron Toponce demonstrates why he thinks that using sha256crypt or sha512crypt on current GNU/Linux operating systems is dangerous, and why he thinks that the developers of GLIBC should move to scrypt or Argon2, or at least bcrypt or PBKDF2. After going into a bit of analysis, he concludes that practically everything else should be avoided, especially md5crypt, sha256crypt, and sha512crypt and many others.

Argon2, scrypt, bcrypt, and PBKDF2 are not software suites, they're algorithms, and each have multiple implementations available. Your concerns about diversity are still valid, but less so, and at a different level.
