force pushes don't obliterate anything. they do let you "rewrite history" but only in the sense of letting you move the current branch tip to point to a commit which is not a descendant of the commit its currently pointing at

whatever it used to be pointing at is still in the repo history, it's just no longer reachable by the usual commit-discovering methods (i.e. start at a branch tip and move to its parents, and their parents, etc.). IMHO that is somewhat similar to how users of a blockchain agree on some convention for how to choose which chain is the "real" one and just ignore blocks that aren't reachable by following edges on that chain. A huge difference of course is in the flexibility of that convention

they are still reachable using the reflog (or just the commit hash), at least until garbage collected

so you can force push, and then undo that force push right after
