Is your feature request related to a problem? Please describe.
I'm always frustrated when we can't specify the minimum number of parts to be laid to disks for a successful PUT. Right now there is no notion of it, for 12+4 policy 16 objects have to be added while in some cases users are OK with 14 (cluster has 16 nodes and one or two are unavailable).
Describe the solution you'd like
Have some EC-specific "MINPARTS" number in policy rule.
Describe alternatives you've considered
Can be a part of initial placement policy, although initial placement is designed more as optimization and currently it just enables/disables a certain EC rule. However it's pretty close in mechanics.
REP rules can also be thought of wrt this.
