The use case was outlined in v1 and maybe missed in v2. This is a "toy"
utility, like 2048, to make it easier to show off things like "I just
made U-Boot work on this new platform". So yes, it's going to bloat the
code size, but it's also not going to be enabled in production (or
hopefully, defconfigs when submitted for new boards...).
