Yes, and that is actually what the user wants. I mean, why would the user set
core.mode=next, if the user doesn't want to experencie incompatible changes? A
user that sets this mode is expecting incompatible changes, and will be willing
to test them, and report back if there's any problem with them.

But that's what we are doing already. Look at the test I wrote, it's testing
the warnings for the current version of Git.

I agree, but he really wants the change, and proof of that is that the warning
is already there, and every Git release since then has an annoying message
about that at the top.

I agree. At first I simply ignored the changes because I didn't have the
patience to figure out what exactly did they mean. Now I was forced to
understand them to write this patch, and I'm also forcing myself to use this
behavior.

'git add' removing files is counter-intutive, 'git stage' (currently an alias
to 'git add') might make more sense.

But even better would be to use my proposed changes to 'git stage', which add
subcommands, for example:

 * git stage all (git add --all)
 * git stage update (git add --update)

But it doesn't seem that patch is going to be applied by Junio, so most likely
we would have to deal with yet anotyer counter-intuitive behavior in Git.
