After thinking a while about how to solve the problems I have, I
consider the following things as a solution to my problem.

Add an option --isolated, -i to git checkout: Check out a branch / tag /
revision but do not touch the index. This could be used together with
--work-tree to check out a branch into an arbitrary directory. Also, it
satisfies all 4 criteria from [1] and therefore is perfect for
deployment from a bare repository.

What do you think about this feature request?

Yours, Robert Clausecker
