I think WB are smart enough to realise that Snyder was entirely to blame for... whatever the hell MoS and BvS were.
No, Superman's future won't live and die on Cavil's involvement, but given he just had his first unqualified hit in M:I6 the timing could have perhaps been better. I think most people would have been perfectly happy giving him another shot at a decent solo film, but hey-ho.
