Just thought I'd mention the possibility. There is something of a grey area between "definately pin control" and "some extra pin hardware duct-taped to something else". I guess that is natural, life is full of grey areas... Basically if there are plenty of pins and functions, local solutions to the problem will not scale. Then it is necessary to go ahead and implement full pin control. Especially for say a big BGA package or so with lots and lots of pins. It is is a few pins or they just alter between similar functionality (like different graphic modes) I think local solutions are OK. There are other problems though, but I comment on these separately.
