My argument is that any Ruby impl requirement should be explicit in the 
gemspec; i.e. it should be possible to install a gem that will only ever 
work on MRI since it would say it only works on MRI. And likewise for 
JRuby...there's already a couple non-platform gems that only work in 
JRuby. Without adding "supported implementations" to the gemspec it will 
only get worse.
