Move the bootcmd commands into a seperate distro_bootcmd environment variable. Allowing a user to easily launch the distro boot sequence if the default bootcmd did not default to distro boot commands.
Well, the user can just type "boot" or "run bootcmd", so I don't think this makes it much easier for the user:-P
Also set CONFIG_BOOTCOMMAND to "run distro_bootcmd" if it hasn't been configured yet rather then putting it directly in the environment. This allows boards to make the distro boot commands available without necessarily default to them or to use them as a fallback after running some board specific commands instead.

As an aside, I actually have a local commit that amends the bootcmd value to include BOOTENV_HOOK_BOOTCMD_PRE before the current value, which also allows boards to do arbitrary things before executing the distro boot code. Still, I think your way is more flexible, since it allows board-provided scripts to invoke $distro_bootcmd when/whereever they want. I'll rework my code on top of this.
