I'm not sure about this. We already have an IgnoreUnknown directive to
skip keywords that aren't supported. Perhaps we could consider adding a
percent_expand() to the include directive or a "localversion" clause to
the "Match" keyword to get this capability in a more general form. E.g.

Match localversion 7.*
  Include ~/.ssh/config/config-7x
