Options are fine. It can’t hurt to have lots of options – as long as one opts in.
The original contract needs to be honored though, and from that base one can opt into other things and accept changes. That would be fine.
As long as the original contract people have already signed up under remains in force, new people can easily sign under a different contract, and all people can choose options they like.
The important part is that there be no breach, no going back on already signed contracts. This is important so we can preserve the integrity of the industry.
New conditions going forth and new options are just fine.
