... if "the company" deserves this sort of commitment ...
I know the term commitment is used quite often, and I cannot say you are wrong, but I simply do not see it that way myself. I think it is simply a matter of "hard landscape" vs "myself" i.e. "external" or "internal" to myself. In my case I put only "external" (hard landscape) things on my calendar. The reason is not the strength of the "commitment", nor the "importance" of the task etc., but simply the fact that I need to renegotiate the "external" ones with others if I want to change them.
If I did use the ploy of making appointments with myself (which I do not) I would probably put those on a separate calendar in a different color, such that I could easily see which ones are truly blocking my calendar (requiring renegotiation) and which ones I can change with the stroke of a pen without asking anyone. But as I said, I do not believe in making appointments with myself. If I want to do the task I will typically just do it, and if I do not want to do the task (something makes me shy away from it) then no lists or calendars or colors in the world can make me. In such cases I typically need to reassess the task - maybe it was poorly worded, or maybe it is not really all that important, or maybe there are some terrible risks with it. If the gut chooses to procrastinate it often has a very good reason.

Folke's use of the term "habit" and suggestion of the tickler is useful here, but, again, this method doesn't seem that prominent in GTD.
It is not prominent, for sure, but it does not go against GTD as long as it is OK to hide task in the "freezer" (tickler) again for another day or so once you have done it. But if you could equally well continue and do a second pass, or a third pass, that same day, then the method loses some of its value and validity. It would then need to stay as a next action.
My primary recommendation would be the "logbook"("journal") approach, and not write anything on your lists or calendars. That is not explicitly covered in GTD either, as far as I can rememeber, but it does not break GTD in any way that I can see.
GTD is actually quite simple, even simplistic at times. You may need to invent things on your own here and there. And David Allen actually encourages you to ;-).
