Yeah, this will be an evergreen request. But I am rather sure it won't happen. This isn't a simple visual novel, there is too much going on behind the pics. And it tries to have a realistic vibe in all its craziness.
You may try it yourself by setting "config.hard_rollback_limit" in script.rpy:26 to something like 10 or 100 and restart. Then run around a little bit. Rollback works somehow, but erratic, slow and unpredictable, at least on my machine. Of course, the dev could set some checkpoints for a week but then the folks will be crying about no content and milking and bugs and so on ...
