Nexus Aurora: Universal Berthing Mechanism, OCS, Orbital Can

Summary of what the thread established

UBM (IAC-21 D3 IP 4 x64597): 3000 mm OD, a 2000 × 2000 mm rounded-rectangle passage, 693 mm deep, ~800 kg, androgynous, with utility interfaces mikelepage, 2024-01-10; lamontagne, 2023-01-24.
Capacity 450 kN, which limits outer modules to ~46 t at 62 m radius and 3.6 rpm mikelepage, 2024-01-14.
Files, Hempsell's Skylon USIS port paper, the Orbital Can system lamontagne, 2024-01-10; lamontagne, 2024-01-10.
OCS (Orbital Colony System) project lamontagne, 2022-10-11. Its specs were used for lamontagne's Space Can ring lamontagne, 2023-01-19.
Critiques. Coastal Ron wants a bigger opening (2500 mm) for two-level 8 m modules, and exterior support frames so hatches never carry loads Coastal Ron, 2024-01-15; Coastal Ron, 2024-01-15.

Will the UBM (or Vast's 2.9 m standard) become the de facto large berthing interface?
