I just don't understand why there are large fractions of the community, fighting to have a uniform syntax without any dialects, not being in favor of e.g. an optional warning to enforce explicit self, which could prevent people from bugs, yet then a proposal with three (!) allowed syntax variations is introduced.

The `where` clause improved readability - it might not have had anything to do syntactically with the optional binding, but it usually made some kind of sense:

guard let myPoint = view.calculateSomePoint() where view.isVisible else { ... }

Seems perfectly reasonable and much more readable than

guard let myPoint = view.calculateSomePoint(); view.isVisible else { ... }

-1 for me.
