No, this is a fine solution, and there is a way to deal with the

Here is a quote from draft-ietf-secsh-architecture-08.txt:

o  Names that do not contain an at-sign (@) are reserved to be assigned
   by IETF consensus (RFCs).  Examples include `3des-cbc', `sha-1',
   `hmac-sha1', and `zlib' (the quotes are not part of the name).  Names
   of this format MUST NOT be used without first registering them.
   Registered names MUST NOT contain an at-sign (@) or a comma (,).

o  Anyone can define additional algorithms by using names in the format
   name@domainname, e.g. "". The format of the part
   preceding the at sign is not specified; it MUST consist of US-ASCII
   characters except at-sign and comma. The part following the at-sign
   MUST be a valid fully qualified internet domain name [RFC-1034]
   controlled by the person or organization defining the name. It is up
   to each domain how it manages its local namespace.
