>>  + recursive submodules: detach HEAD from new state

>>  "git checkout --recursive" may overwrite and rewind the history of
>>  the branch that happens to be checked out in submodule
>>  repositories, which might not be desirable.  Detach the HEAD but
>>  still allow the recursive checkout to succeed in such a case.
>>
>>  Undecided.
>>  This needs justification in a larger picture; it is unclear why
>>  this is better than rejecting recursive checkout, for example.
