We seem to be splitting hairs here. Why are we providing tech preview to
advanced users? Are you saying they construct expressions directly using
internal APIs? I doubt thatâs tech preview.
Users can construct a lot of invalid plans that lead to weird semantics or
behaviors if they try, and this doesnât really make it worse.
In either case itâs not that difficult to remove them and add them back so
I could see it going either way.
