"all the limited busybox commands would be replaced" would be a huge 
list from dc through gawk, minicom and wget to vim.

And would vim-tiny qualify as "the full featured command" of busybox vi,
or should this include vim with full features?

The nice thing about busybox is that it is so small,
in many cases one full featured command alone
is bigger than busybox.

It is not obvious to me what usecases people have in mind for
getting rid of busybox, and whether everyone is aware that
something like "all busybox commands replaced" is *very*
expensive regarding filesystem size.
