To me it looks like having the timing for each step is enough (schema.org already supports that).

You can then _decide_ what to paralellize (maybe you want to take it slow, maybe you have another person to help you, etc).

To me, it sounds way simpler. Specially for those writing or annotating the recipes. You're thinking of the reader, but the writing is important too, it's the hidden cost of making super detailed models.
