Is V4 really recommended for general use?

If you stick to C-git, I do not think there is any reason to avoid
it.  It is already a mature technology, the difference between 2 and
4 are so trivial that it is very unlikely for a latent bug to be
hiding in corner cases.

It is a different matter if various reimplementations already
support the format.  You can try it out, and if you find that other
tools based on reimplementations of Git you use do not understand
the format, you can safely go back with

	git update-index --index-version 2

after you upgraded to version 4.
