Well, reasonable, but how would ATC know who's who? I fly fairly often and, the way the controllers speak to me, they don't realize 3R9 is my home field (they're absolutely polite but, for example, they always ask me if I need the phone number to cancel on the ground; the number I called to pick up the clearance earlier). Plus there are many pilots based here who are rusty IFR flyers at best, so if AUS was to base it on where the plane is based, even that wouldn't help.
It seems the only practical way for such pilots to avoid a prolonged ODP is to ask if they can shorten or bypass it. Honest question: is that permissible when picking it up on the ground? I imagine I could ask for an amended clearance and the clearance per se could be amended while I wait on the phone but, if it happens as it does here, by being part of the release rather than the clearance, can I ask for the release to be amended? I've never done that and never thought about that as an option. I suppose I could depart VFR and pick up the clearance in the air but we've already noted that scraps the ODP anyway, plus it requires VMC.
