Ok, Project From View has an option to correct aspect, so it's not so
bad. However, UV projection produces distorted maps, see
http://www.pasteall.org/pic/show.php?id=38001 (blend file:

Such mesh was created only to demonstrate exaggerated distortions, but
those exist for any non-flat mesh in perspective mode. Project from
view and Uv project work almost perfect in orthographic mode (there
are some distortion for overlapping faces which I don't take into
account), but both of them produce distorted uv maps for non-flat
meshes in perspective mode. On the other hand, sticky produces clean
image like if it was composited over the 3d image.

New options for object modifiers are always welcome :)!

New tools are also welcome! Err, actually this would be rather old
tool. Also the same tool could be used in do_versions to convert old
sticky coordinate setting to uv maps (if it is even possible, see the
image above)
