I certainly support that last sentence! My understanding for your 1) is that you are NOT going to plug in LNAV/RNAV and unfold the crossword page if you have 'constructed' such a procedure but that you are essentially flying raw data tracks with a map display for 'comfort'?
I once built one particular 'qualifying' SID out of either OSL or ARN (cannot recall which) and tried it in LNAV in a 737-300 'for fun' (in VMC) - it made a complete hash of it!
