I've worked on mission planning software for parachute systems and the precision we can achieve is already extremely high. Given how poorly this seems to scale, the only use case that makes any sense to me would be something like sensor drop, which are the only payloads small enough for these chutes. Or potentially for drogues on multi-stage systems, but I'm not sure they'd even be useful there because usually a fast descent is part of the appeal of a drogued payload, and not just to reduce time exposed to wind drift (e.g., to reduce time it is vulnerable to enemy fire).
