1) In the previous topic we discussed rotation exceeding 90 degrees. I am not exceeding 90 degrees here.
Let me quote myself:

As I'm afraid that 90° may still be unstable I would even go for a rotation of -0.001°
2) I have not mixed inside and outside of the sketches, I have _only_ translated along Y. If in doubt please try using the attached file 'VentManifold 3.FCStd
Even at y=16mm the loft is not ok. If you hover over the sketches you will see in the status bar that for the vertical sketch the inner edges have higher numbers than the outer sketches. This means that you made the outer slot first and the inner slot later.
With the horizontal sketch it is vice versa: the inner slot has lower edge numbers than the outer. These images show some z-fighting, indicating issues on the surface:
You state here that loft uses the shortest connections. Pure translation along Y do alter the shortest connections and should not give 3 completely different, seemingly non-deterministic, solutions to what basically is the same loft.
This is just a guess, and as stated above, the loft is broken in all 3 cases.
4) Users should not have to go through all kinds of workarounds to perform what should be a trivial operation.
Calling a loft "trivial" is open for discussion, but you are perfectly right, that users should not have to use (rather complicated) workarounds for such things.
