After seeing multiple "first drafts" going into production over years, I've internalised that they shouldn't be even presented as ready to be shipped until and unless a draft passes multiple refractors. If something is unknown, it is better to explore possibilities and prototype in a prior sprint before picking the actual implementation. Take your time to figure out unknowns before writing the code you intend to ship.
