I Am Now Even MORE Convinced ...

 ... that, as I've hypothesized before, the John Wick film franchise takes place in the Matrix universe.

Why? Well, for the TL;DR, see this piece by Dan Seddon at Digital Spy. Short version (Warning -- spoilerish material!):

"Tiffany's" (actually Trinity's) husband, Chad, in The Matrix Resurrections is played by ... Chad (Stahelski).

Who was also Keanu Reeve's stunt double in The Matrix and stunt coordinator for The Matrix Reloaded and The Matrix Revolutions.

And who directed the John Wick films.

Chad is clearly a major figure in the Matrix universe, used by The Analyst to supervise/control Trinity after previously having been substantially responsible for Neo's actions. ...

And the John Wick universe is basically entirely his (although Morpheus shows up in it as a fly in the control ointment).

Presumably that universe was a side Matrix project (a "modal?"), dedicated to helping work out / excise some of Neo's violent and obstinate tendencies as he was re-made into Thomas Anderson, neurotic game desiger, after Revolutions and before Resurrections.

And Chad, in between assignments coordinating all the violent action in the first three Matrix stories and acting as Trinity's supervisor/controller in Resurrections, was given the Architect role in that side project while the Analyst worked on the new, improved Matrix.
