Canon changed (not redesigned) a number of non-L prime FD (manual focus) lenses in 1988, to create the auto-focus EF series. Other lenses changed at this time included the 24mm f2.8, 50mm f1.4, and 50mm f1.8. Canon threw out the metal barrel, added a polycarbonate barrel, and auto-focus motor and released the same basic lens design. At that time, only the 28mmm f2.8 actually changed lens formula.
The same EF non-L primes Canon sells now, were actually designed somewhere in the distant past, say 1965-1970. Canon has been milking these unchanged designs for more than 40 years, without spending a penny to update them. Do you think they would lower themselves and actually throw out the arc form drive motors and add USM and improved optical coatings?
I think, no. If you looks at new Canon lens designs, for the most part, they will not update a lens that sells for less than $1,000.

Besides the lower shutter speeds you can shoot at with IS implemented (think of times when a tripod is unavailable), there are plenty of people out there who do not have the ability to hold their cameras steady due to old age/ailments ect ect. Bedsides, would an IS version of any lens stop you from using a non-IS version? The same applies to those crying about the idea of IS in a WA--how wouldn't it be useful?
