Loft between a point and 6 control point degree 3 curve.
Surface deviates from curve depending if order of input selection is reversed.

Loft, Straight sections, Do not simplify.
Curve selected first, then point.
Results as expected with edge of loft exactly matching input curve.

Surface edge deviates significantly from input curve.

Hi David - checking it, thanks.
I see that if I MakeUniform the curve it works as expected.
It seems to depend on the end of the curve that is picked as well.
It looks like it is just getting the curve end wrong - no way to sort the ends in the usual way with a point as the only other input, is my guess.
Thanks for pointing this out.

@pascal Thanks for the response and putting it on the heap. For me it should be relatively high priority as it is a flaw in a fundamental command. This time I happened to notice the problem immediately after creating the loft this time. Previously I’ve had previous problems with lofts which were created using a point (ie general conics) not matching other geometry created using the same curves. Now I know the likely reason for the error in the surface shape.
