Question to developers: When is two-point perspective going to be available in Octane?

What do you exactly mean about 2PP?
As I understand 2PP is the kind of perspective you get when the camera and the target are at the same height parallel to the ground, with an exceptional case of 1PP that is a 2PP but wher the XY perspective point are coincidental.
I may be wrong though!
So that saind this is alreaydy "implemented"
Cheers

Two point perspective is related to drawing and has nothing to do with 3D, basically you have two vanishing points. In 3D you can use 1,2,3p or whatever you like, whenever you like. In other words, the 3D space is already defined for you, you don't have to define it yourself as you have to do in drawing.

This is one of the weirdest features I've ever heard requested for a 3d app.

perhaps it is not well explained but it is not weird at all to be!
In Archviz it is called Vertical perspective correction. Purpose is to get vertical lines of a building to stay parallele.
It is a major feature in Archviz. It is simply undispensable in that field of rendering.

I knew I should have explained better.

This is available for example in Yafaray, as just a one click option.

In reality there are three vanishing points ("left, right, and up or down"), but in architectural visualizations two-point perspective is often used. This means that the "up or down" point is missing and all vertical lines are actually vertical in the image. This is not real but architects seem to like it.

afaik, that's called "architectural camera" in other software

Ah, in photoshop it's called camera distortion correction.

yes, or 'architectural perspective'

I think it should be the lens shift option Octane has...
