One does not need BPF to transform devices into something new, that is easily done from userspace. All that you need to do is to run a daemon that grabs the original device and creates new virtual device, you can get the idea from https://github.com/metan-ucw/evfilter

I'd rather not need letMeTypeThings.d to be running if I want to work on my computer. In a recovery shell, letMeTypeThings.d might not get started, for instance.

I fail to see how that is different from let_me_type.bpf not loaded before executing recovery shell. Either you have drivers and workarounds compiled in the kernel or not in which case they may fail to load.
