Can you share examples of that?
I added a comment to the PR you mention (to flesh out my 2017 comment on the connected issue) about why it is important to have a second mechanism for variables.
Many changes are one line (like removing this phase of compilation) but such changes often have more complex implications than the line count might suggest. Perhaps you can start a new thread sharing examples of where you think it might be good to have this feature, so others can figure out if there really is no other way to proceed than by adding a 2nd mechanism for variables that lacks type safety or even name checking. That would help me understand this scenario better.
