* git-push to update the checked out branch will be refused by default

  Make "git push" into a repository to update the branch that is checked
  out fail by default.

If this is implemented, it shouldn't, in my opinion, be a default
setting. I regularly push to checkout repos when I'm doing cross machine
development. However, I could live with a configurable setting as
proposed in the given URL. I think Git should not be too cautious about
following users instructions. The user knows what is best for him/her ;)

It is already implemented; the proposal is about setting the default.
The plans for 1.6.2 are already to issue a warning and ask the user to
set the config variable to shut it up.

if this is going to be done the timeframe for making the change should be 
quite long. think in terms of debian stable or RHEL, whatever version they 
ship is what their users are going to use. it doesn't matter how many new 
versions and what warnings you have the produce in the meantime, the users 
won't see them.

to the progression needs to be

one upgrade cycle the user is using the old version with no warning.

next upgrade cycle the user is using a version with a warning.

the third upgrade cycle the user is using the version with the default 
changed.

the problem is that these upgrade cycles are 3-5 years each, and it's not 
unusual for the types of users that use dbian stable or RHEL to be running 
these systems in places where they do not get patched during their 
lifetime.

note that this isn't always stupid to do, if you are deploying them on a 
network with no Internet access the stability of knowing that things are 
_exactly_ what you tested may be worth more than updates that close bugs 
that you don't hit or add features that you aren't using (or introduce 
unexpected changes like spitting warnings or errors for things that the 
old version didn't, which is exactly what is being proposed.
