Surely I can't be the only one who uses this. I am not looking forward to copying & pasting a reimplementation of the comparison functions into every single project I work on.

Can you give some examples as to how this will have such a huge impact? Now that we have the ?? operator it seems that this is fairly easy to replace:

	value < 5 // where value is of type Int?

With:

	(value ?? 0) < 5


The latter is completely clear what the behaviour of nil is.

Also, you can still re-add the operators where you need them, ideally with as limited a type as possible so you can make sure that it's behaviour is well defined.
