The biggest lack is something like 'genfatfs', mcopy is a step in the right direction but is too limited to work in this scenario.

But this is just to be able to generate a packed image that can be
copied directly to media?  Maybe that should be a different image
type, like the .u-boot images?  Then it would be obvious what's
being done and why.  In my case, I'm more than happy running a script
to copy the appropriate files to my SD card, etc. and I don't care
(nor especially want) a packed image.

Fair enough, I'll try to keep the discussions where they are most relevant.
