Nope. No plans to make them essentials as they have no importance beyond travel convenience.
But that IS important --- so important that it's the primary feature of the mod! Why would someone go through the trouble of downloading, installing and testing out this mod, knowing that it might all go poof when some super mutant decides you don't
need a Morrowind style travel mod? Who is HE to tell me what mods I can use and what I can't? Anyway, from a design standpoint, I pretty much completely disagree with this. If it was purely an immersion mod, that's one thing. But it's an immersion mod with utility. Utilities shouldn't be able to die. But it's your mod obviously and you have to design it as you see fit. Anyone who doesn't like that can very easily change it in the GECK (which is precisely what I'm about to do.
) Anyway thanks for the mod and very much looking forward to trying it. Now, I too finally have an excuse to disable fast travel.
