I think there are two major concerns with this that need to be addressed.
1. Is it physically possible to adjust the programme for individual players?
2. If it is possible, how do WGT ensure only those who are genuinely lesser abled get the wider sweet spot (or whatever other allowance is made). I would think the minimum would be a doctors certificate listing what your ailment entails. This of course would then lead to concerns over the security of the data they hold on you, (sheesh we've been down that route before).
However, if both of those issues could be addressed I would cautiously welcome any such move.
