> 2. You want to keep producing work while the first PR is in review. So you stack subsequent PRs onto the same branch.

Instead of using the same branch, make new branches from that parent and commit there.

The cool thing about that approach is that (at least in git-tower app) is when you edit a parent branch after pr comments, all those new commits will be automatically “restacked” on descended branch (children branches will be rebased on new state or parent, incorporating the hew fixes)
