Except with cloning the other twin would be a different age as with current tech the clone is back to being a baby. You'd need rapid growth tech and mind transfer tech to at least make the clone have the same age, memories and personality, although that would most likely introduce other differences.
There is at least one case of parents, told at a very early stage that they're expecting twins, deciding to remove and freeze one of the embryos for later reimplantation, so even with actual identical twins, they can be different ages.
But yes, transferring minds is not something we can do. I'm not sure it's something we'll ever be able to do.
Should it actually become possible, I assume that certain parties would even advocate for the unique life/lives of the clone(s). The argument would be that the clones' chance at life shouldn't be overwritten by other being's attempts at extension of life.
"Ethical minefield" doesn't even begin to cover it!

So, less than an identical twin is the same person. The criterion above still holds.
Nothing more than bootstrapping the data for some integration testing
