I've shifted to focusing on repo == team. If your organizational structure is to have many little teams that are independent from each other, then you build your source code management to reflect that.
I built my engineering staff to focus on any of the initiatives that my boss hands to me (changes week/week) - so we went monorepo so we could move between those projects/apps/programs quickly.
We knew that we didn't want to pay the maintenance cost just because microservices/multirepo was a buzzword AND we wanted future ventures to get faster (example: we solved identity for authn/authz once and now every app that needs it after can leverage it and we can upgrade identity and all of its consumers in one pull request).
This is my conclusion too. Team becomes fundamental entity and projects/products belong to teams. Everything the team produces stays on the team's repo. So you always know which team owns what. It is also easier to review, supervise and clean up.

Sounds like that would enforce Conway's Law a lot and make cross team collaboration more difficult.
