Can we please deprecate the 'version' argument of registerStep?

This is the interface description:

    o 'version' is a string for comparing versions, it is preferred to
      be a yyyy/mm/dd-ii formatted string (date plus two-digit
      ordinal).  when comparing two version strings, the version with
      the lower sort order is considered the older version.

      - Newer versions of a step supplant older ones.

      - Attempting to register an older one after a newer one results
        in a KeyError.

AFAICT this feature was never used, became inoperable after adding extension profiles and makes absolutely no sense in a global step registry. Originally steps were linked to specific files in the profile, the 'version' described the version of the XML files.

A profile version can now be set in metadata.xml. AFAICS this supersedes the import step version approach.

Am I missing something?
