Well, as I mentioned there was already in 2020 the problem of (human-generated) slop commits causing unnecessary work for maintainers.
The commit in itself might add some minuscule value to the project, but when you take into account the time it takes to check the commit and approve it, you're probably back at negative value again.
Plus, there's the problem of people doing this in an adversarial way. How can you tell whether a random commit touching 100 files is the work of an enthusiastic beginner, or a malicious hacker that's hidden a subtle attack somewhere? Well, you need to spend your time carefully checking it.
So it's way more pragmatic just to set up some automated filter to put all of this stuff in the bin.
Oh and by the way:
> I wouldn’t think a commit fixing typos ever attributed merit to a developer.
