Note that for most it still requires industrial composting to really decompose, and a bio-plastic bag in the ocean will be just as bad as a regular one.

Curious if you could provide justification for this; do you mean that an animal could just as easily choke on a bio plastic bag as a petro plastic one?
My non-biologist assumption had been that compostable plastic would just take longer to compost without the heat and high activity in a commercial situation. IOW, I think that we need to assume some fraction of manufactured stuff will always end up in the ocean, so it's better that is made from bio- than petro- materials.

There are others.
