Debian alone lists 225 packages depending on libgcrypt.  And there are
for sure many more users.  All these packages would need a rebuild and
the maintainers need to go over it to figure out whether the change may
affect them.

You don't change an ABI if there is not a serious reason to do that.

Those who want to list "AES-128" instead of AES may easily use a wrapper
like

  const char *
  cipher_algo_name (int algo) 
  {
    if (algo == GCRY_CIPHER_AES)
      return "AES-128";
    else
      return gcry_cipher_algo_name (algo);
  }

We can't know.
