I'll just say this.  I don't see this as an issue of escalation.  The power creep is already here.  Because switching lockers is such a pain, people already only stock it with the most efficient and powerful items available.  Having the freedom to experiment with a Bloody Sigil prep isn't exactly going to cause a power spiral.
And like I said in the first post, we already have a functionally unlimited locker, it just costs 10-20 minutes of real time to access.  I don't really buy into the slippery slope argument that having a hassle-free inventory system will open the door for anything other than a hassle-free inventory system.
