If the old command-line is ever going to be removed, there's no point
supporting both at all; I'd have to hack my scripts to support both
sometime, so I may as well do it now rather than wait.

Yes. I own some scripts that build U-Boot, and they need to work on any
reasonable version of U-Boot that anyone might want to build. For
example, they build 2014.07 just fine, and there's no reason they should
ever stop being able to do that. I obviously also want my scripts to be
able to build any future version of U-Boot.
