"unnecessary" is in the eye of the beholder. I would have though 
"unfeasible" would be a better criterion, in which case "diff -y" would 
have to be implemented. It does not appear to be unusually difficult to 
implement that option (which requests side by side output).

What psychologists call "projection" is widespread in open source circles, 
where it manifests itself in statements that amount to "I don't need it, 
therefore you don't need it, and your request for it indicates your bad 
character". We should have more respect for legacy environments, which may 
well depend on features of the software that the current core team no 
longer, or never used, but which will discourage users from keeping up 
with new versions of FreeBSD and which will eventually move them to Linux.
