I don't think anyone wouldn't agree that being able to work deeply on a single async task would be a great benefit, but your reply completely ignores the issue OP brought up:

> Stacking in my personal experience usually leads to merge conflict hell as changes and PR suggestions get merged underneath you.

That's been my experience too.

And beyond the technical issues, the deeper you work on a single issue the more at risk you are of the simple issue of finding design or requirements issues in the base MR that require going a different direction and discarding the whole stack. So even if you can somehow avoid conflict issues, stacks are still dangerous.
