Stacking is good for expressing dependencies, but isn't helpful when you need to make several distinct changes that aren't necessarily needed unless you take them all in. What's the value in having a separate PR that introduces a framework that you later use in another PR when you may not actually want to merge it if the latter one doesn't end up being merged as well?

A PR is a group of commits, just utilize that when you need it.
