Historically, the idea of rubygem(foo) was that rubygem(foo) should
correspond to require 'foo'. However, I am not sure that this was always
true, since this was definitely underdocumented and guidelines stated
that you should provide rubygem(%{gem_name}) instead. And the question
is if we should support this or not. This might be useful for some gems,
where the name of gem differs from the require-able file, for example
rubygem-bcrypt-ruby comes to me mind.

When we overhauled packaging guidelines during migration to Ruby 1.9.3,
nobody remembered the history correctly and FPC decided to drop the note
about rubygem(foo) require.

With regards to comment [0], I would argue what is new or old syntax.
They are both legal as long as they are satisfied IMO.
