That's actually been brought up in the discord, and one of the devs (NB) is mulling it. The problem is that each level of rollback is essentially an entire save object, so allowing 20 clicks backward increasing save files by 20x. Now each save file is only about 15k so that's not a huge deal (in my case my save folder would go from about 20MB -> 400 MB), but it will probably make some people sad if they are on tiny devices or maintain massive save folders. I believe his proposed solution was to make the saved rollback depth configurable.
Not sure when that patch is going to make it into the release, but once it does we will be able to grab at least some context when loading in after a month of hiatus.
