This is one way of looking at "the problem". The other way to look at
it is that things are merged too quickly / without enough review, etc.

That is the problem kernel maintainers can actually do something about.
Or, they can just whine about "not enough review bandwidth".

There has been this complaining from lots of people about not enough
review bandwidth for quite a few years now. So I doubt it is going to
magically get better by making more noise.

Consider that there is probably virtually limitless amount of crap that
people want to try to merge, so there is always going to be a lack of
review bandwidth if the aim is to merge as much as we possibly can as
fast as we can.

The answer is to not make the problem worse by merging stuff faster
than can be reviewed. When that happens, developers and companies
should eventually assign a higher value to patch review.
