is there a reason why loads of people are gimping themselves by using focustarget instead of targettarget?

[Simulacra]

I think the title says it all

I've noticed a general shift away from targettarget in the last year - why is that? Is it because all the example macros use focustarget or is there some other reason. Has everyone forgotten targettarget? Why would people use focustarget when targettarget is plainly superior?
