Note that beside "disjoint" merges ("cross project merges"), of gitk,
git-gui, gitweb and (very early in git history) git mail tools, there
are also three "disjoint"/"unparented" branches: 'html', 'man' and
'todo'.

While 'todo' is totally unrelated, and if instead of starting in
separate repository it would be created using proposed feature, it
would be created with "no common paths" case.

BUT in the case of 'html' and 'man' branches I could see why current
implementation of _removing index and not removing files_ might be
advantageous.  Remove index, create HTML and manpage version of
documentation, and add HTML (in 'html' branch) or manpages (in 'man'
branch)... probably shifting root, so it is not all in single
Documentation directory.

Just my 2 eurocents.
