Sure, which is why it needs to be cleaned out regularly. This isn't much different than with /var/logs or even /boot. The former can suck up lots of disk space for no reason and the later can use up limited space if you install to many kernels. I don't know, I am not a fan of this policy in the kernel, I would rather keep it simple, like an on/off switch. If you decide you want to use efi for logging than you better make sure you have an app to clean it up. Otherwise the user shouldn't turn it on. Creating rules like this seems to be complicating things to me IMHO. But I will gladly defer to someone else's judgement.
