IMO there's no reason to recompile an app that has no need to be 64 
bit, just for the sake of making it 64 bit. You gain nothing by doing 
so (other than a marketing bullet) and it could potentially make your 
app bigger and slower.

Bigger because you're now making some things that only took 32 bits 
take twice as much space. That not only means more HD space but it also 
means less info can be held in the processor caches (essentially 
reducing their effective size) resulting in more bits needing to be 
moved around more often. That means slower.

How much of a detriment (if any) this would be is really hard to say. 
It could be trivial or significant depending on the app in question.
