Oil on paper is perfectly acceptable and permanent as long as the paper is properly sized. As you noted, there are a number of sizes which have been used over the years. My favorite is a dilute technical gelatin solution into which a small amout of alum is mixed. The alum hardens the gelatine (as well as most gums, starches and glues). It doesn't make it brittle but it tends to tighten up the glue. It's also great for sizing paper for general drawing, and in particular, drawing with ink.

Shellac is fine as long as you get a de-waxed shellac. The very best quality is called dewaxed Super Blonde and I have seen the flakes for sale on the internet. As with all shellac, it should be mixed fresh. The already mixed shellac in the can is usually too old and it still has the wax in it.
