Description
T1?|T2? is now parsed as T1?, whose correct form should be (T1|T2)? or T1|T2|nil or field? T1|T2.
But many libraries (e.g. neovim plugins) are using this incorrect form.
This misuse is so prevalent that should we consider making this form legal?

Research direction
The issue does not name a file, test, or entry point. Begin by locating the parser handling for T1?|T2?, then determine whether the language should accept that form and how it should relate to (T1|T2)?, T1|T2|nil, and field? T1|T2; completion requires an explicit syntax decision and corresponding parser coverage.
