Since that can lead to data loss, which should never be enabled by an
option other than --force.
I suppose that using --trust was in some situation, safer than --force,
because it doesn't entirely disable checking for data loss, but only
disables checking involving data that is on the specified repository.
But it seems better to be able to say that data loss only happens with
--force.

This is conceptually very simple, just making a 1 that was hard coded be
exposed as a config option. The hard part was plumbing all that, and
dealing with complexities like reading it from git attributes at the
same time that numcopies is read.
Behavior change: When numcopies is set to 0, git-annex used to drop
content without requiring any copies. Now to get that (highly unsafe)
behavior, mincopies also needs to be set to 0. It seemed better to
remove that edge case, than complicate mincopies by ignoring it when
numcopies is 0.
