The handling issues has mostly to do with weight rather then size. If someday the iPad 9.7 has much less bezel, half as thick, and much lighter. Would that still be a problem?

I think that is where iPad is heading. Some argue Apple is obsess with thinness, personally I think both iPhone and especially the iPad has a long way to go before it is Too Thin.

Nope, the size is the big thing. Weight is a factor but the mini is a good size for holding. The 9.7 will always be more awkward than the mini. So, yes, a lighter 9.7 does not replace the mini. That argument is the same as saying a lighter 12" could replace the 9.7 which doesn't work because the 12 is painfully awkward to use.
