As long as all the information is on the drawing in an understandable format, I don't really care what projection is being used.

For anything I've designed on the computer, I'll create a drawing with only what information I know I'll need to machine it, which will most likely only include a single view with dotted lines where needed.
However I use the newer version of BOFP for most stuff, know as the RBOP (Random bit of paper), or if I can find one, a notebook.
