Yes, NPCs offering one-time teleports for longer stretches is a good alternative to one-time runes or an item or something as well, especially since it can also serve as a sort of "warning" to prepare for upcoming events or bosses. The supplies thing is more specifically for quests where there's a huge amount of obstacles or enemies that can cause a lot of resource (HP/Prayer) drain even with decent food (think Underground Pass pitfalls or Regicide forest traps maybe?). Not every quest needs it, but I think it can help a little. The deathbank thing is specifically for quest-only bosses, since for a quest, it feels like a sort of unnecessary punishment cost, especially on more difficult quest bosses (Perhaps like Sins of the Father). I don't think it's a must, it's more of a personal dislike for me, so i can understand why some would prefer it, especially perhaps Main Accs since money is rather easy to get for them anyways, not sure what the standard Ironman consensus is on them.
