I agree that it should be easier to specify straight lines, in any direction. As I see it the key problems are 1) only the rectilinear projection displays all straight lines as straight; 2) if the source images are not already aligned (which is the expected case for purposes of this discussion) then you need a separate straight line on each image to specify how they should line up.
So it seems to me the solution must involve showing rectilinear previews of one overlap region at a time, and giving the user the ability to position several straight lines on it -- say in a different transparent color for each image. That done, the s/w could easily generate a bunch of straight line CPs. A 'blink' key, to switch the view between individual images and the composite, would be a great help. There would also need to be a nice intuitive way to grab one line with the mouse and hold it despite the blinking. And of course the mouse would have to both position and rotate the line -- 3 degrees of freedom. IMHO, it is silly to try to draw the curved versions of straight lines on, say, an equirectangular preview, and just as silly to discard straight lines just because they don't happen to look straight on such a preview.
