One of the problems with this is that it takes quite a bit of calculations to figure out if a surface intersects itself or not.

So to allow for this would tend to cause the booleans to slow down quite a bit...

Maybe there could be some kind of a switch to turn this on so that it would be off for regular use. But it is also a bit hard to set up options like this for Booleans, Booleans don't tend to have a lot of options like for Union for instance you can just select your objects and launch Union, you never actually see any other UI for it...
