An alternate viewpoint:  I would prefer that /bin/sh remain as lean and
mean as possible, conforming to posix and especially NOT becoming
bloated with interactive usability stuff.  If you want a user-friendly
bourne shell and can afford the memory and cycle bloat, use bash. 

Please keep /bin/sh lightweight for embedded and dedicated-purpose
systems that need a posix-conforming shell without a ton of overhead.
