I can also recommend rather to use the stacked PR approach. We have it since years, PR review "issues" are not a thing for us.

I still encourage do to a lot of small commits with good commit messages, but don't submit more then 2-3 or 4 commits in a single PR...

I see stacked PRs as independent of this. PRs are a good unit of cohesion of changes, particularly changes that only make sense if later changes are also merged.

stacked PRs are wildly reviewer-hostile, please do not do them
