it is not a philosophical debate against the auto-squash. It is just auto-squash deletes potentially useful data automatically and provides zero benefit? Or what is the benefit?

1. pr message doesn't contain _all_ intent behind each change while the commit did cover the intent behind a technical decision. would you put everything in the pr message? why? it will just be a misleading messy comment for unrelated architectural components.

2. you branch from a wip branch - why? just. - now when the original branch is merged you can't rebase as github/lab messed up the parents.

3. interactive rebase before merge works fine for the wip wip wip style coding. But honestly wip wip wip style happens on bad days, not on days where you are executing a plan.

4. most importantly: you can read the pr message stuff if you filter on merge commits, but if you auto-squash you lose information.
