I've disabled the use of unsafe features (Jinja extensions, migrations, and tasks) by default and added a new CLI switch `--UNSAFE` which enables them. Templates that don't use unsafe features are unaffected by this change. But Copier will raise an error for templates that do use unsafe features unless the `--UNSAFE` flag is passed.
I've not added an interactive prompt that asks for consent for using unsafe features because I think it's not clear how to distinguish between interactive prompting and raising an error when `--UNSAFE` is not passed. For this, I think Copier would need a switch that clearly states whether interactive or non-interactive mode is desired. Currently, `--defaults` implies this for questions.

BREAKING CHANGE: Copier raises an error when a template uses unsafe features unless the `--UNSAFE` switch is passed
This new command allows to reapply a template, keeping old answers but discarding subproject evolution.
It is useful when there are bugs replaying an old version of the template, or when the subproject has drifted too much from the template and you need to reset it.
BREAKING CHANGE: All CLI calls to Copier must now include the subcommand as the 1st argument. For example, `copier` must become now `copier update`; also `copier ./tpl ./dst` must become `copier copy ./tpl ./dst`.
BREAKING CHANGE: All flags must go after the subcommand now. For example, `copier -r HEAD update ./dst` must now become `copier update -r HEAD ./dst` or `copier update ./dst -r HEAD`.
BREAKING CHANGE: Automatic mode removed. Since now subcommands are required, the automatic mode is removed.
BREAKING CHANGE: Deprecated `copier.copy` function is removed. Use `copier.run_copy`, `copier.run_update` or `copier.run_recopy` explicitly as needed.
