How about follower's back sacadas? Led of course!
Weirdly, I find those less troublesome than follower front sacadas.
Followers walk backwards for most of the dance, so all but beginner followers quickly develop fair back-step technique: fair timing, fair placement, fair extension, etc. Many rapidly become good or excellent. If you lead a follower back sacada like any other step back but just happen to be there to create the illusion of being displaced, it generally works. The only serious challenge is generating overpivot, but my experience is that followers more often pivot too much than not enough.
Whereas the way most leaders in most communities lead, there are few follower front steps that aren't curved somewhat, as in a forward ocho or the front step in the FSBS of the molinete, because normally, a step forward is designed to go
around the leader somewhat. So, when a front step is led directly at the leader, followers tend to veer off or even come up short. This makes follower front sacadas tricky. Yes, this could theoretically affect back sacadas, but the follower can't see you there, so there's no visual wall to make them veer off.
In a follower sacada workshop with Pablo Inza and Sofia Saborido a while back, pretty much all the followers got back sacadas, but most balked and pulled up short on front sacadas.
No comment on side sacadas. I find them mostly "just there" and everybody accepts them on both sides of the dance. Probably because they don't have to go-power of a front sacada or the blind mule-kick risk of a back sacada, they're the easiest, even if most people cheat them as slightly turned front sacadas.
