I think the discussion isn't about prior to battle day. It's about prior to prep day.
That said, every serious clan has requirements about who they'll put in their spin. The logical conclusion of eliminating engineering's impact on the prior to prep day conversation (with an amazing matchmaker that's perfect!) would be to completely eliminate the need for any sort of requirements about who is put into a spin.
Certain things like Heros up for battle day (if needed), good attackers and base designs would persist, but the requirements for 20/20 at TH9 would be moot. 10/10 wouldn't hurt you if the matchmaker were the idealized perfection.
This is the point that a lot of anti-engineers miss. If the matchmaker is perfect, there is no point to clan account requirements as it pertains to battle day.
Note that some clan requirements work as a filter for seriousness or dedication (minimum donations, minimum heros even) and those requirements are often a proxy for factors that matter. However, the actual items that are the proxy aren't important. (so 10/10 is just as good as 20/20 with the same player for a clan, although the types of players with 20/20 are different than the types of players with 10/10, so have to be careful of selection effects)
