you say that firmware isn't maintainable, what do you need to do with it?
you don't expect a device to have it's interface with the system changing on you. modulo bugs you want the devices interface to remain the same, and you want it to be the same as every other version of that device.
besides, a device that you had firmware each install is easier to tinker with then one that has it's firmware in flash.
1. firmware in flash useually requires dos/windows to update
2. updateing firmware in flash runs a real risk of turning the device into a doorstop, if the firmware is downloaded each initialization, all you need to do is to reboot and try again (unless you manage to physicaly damage a device, but that risk is the same in either case)

Aye, there's the rub: You don't really know until you need to do it.
Maybe you need to adapt it, to make the device to behave differently, in order to meet your needs. Maybe you need to study it, in order to improve support for other similar devices from that manufacturer. Maybe you just want better performance on one aspect. Maybe you need to share it with someone else with a similar device who wants a similar adaptation.
Or, you point out one reason yourself:
> you don't expect a device to have it's interface with the system changing on you
I've seen devices where there's a choice of N firmwares that you can upload and some of them seem to have different interfaces to the others, using different drivers on the kernel side. Maybe we'd like to make all the firmwares for that device use a stable interface? We could do that if we could maintain them.
You're quite right that uploading each time is better in some ways to flashing, but some dealers will flash devices for you if the alternative is a 'not fit for purpose' return of goods, so it's not clear cut.
