The pipeline proposal has multiple syntaxes right now that the community is trying to pick from and discuss.
The chances that the F#-style syntax will be chosen AND will make it to the language proper unchanged is VERY low in my opinion.
And if the community goes in a different direction, it's unlikely that the F# style will be maintained for all that long because it's still such an early stage proposal.
Well working Codemods are difficult to make in many cases, and unless someone is paying for it, I don't think there will be many calls for one to translate between the syntaxes unless the proposal gains a lot of usage without settling on one.
