Issue #4233 has been updated by mame (Yusuke Endoh).

Target version changed from 2.0.0 to next minor

Thank you drbrain for the explanation!
Recently, nahi is not so active.  So, I'm sorry but I recognize this as a (bad) spec of 2.0.0.

 Is it intentional that when used via `autoload`, `require` can't handle Gem names?
 
     run@desktop:~/mir/ruby$  ???  ruby -e 'p require "nokogiri"'
     true
     run@desktop:~/mir/ruby$  ???  ruby -e 'autoload(:N, "nokogiri"); p N'
     -e:1:in `<main>': cannot load such file -- nokogiri (LoadError)
=end
