I agree that this could be viewed as bad. However, this is way less of an issue than Google taking choice away, which is what the great-grandparent comment was about.
You're not saying anything new as far as I can tell. Your grandparent already said what you said. I only disputed the "this costs next to nothing" part, which you don't seem to comment on.
Squashing for example allows me to have a history where each commit builds. This has been very useful for bisecting for me. I wouldn't call it "next to nothing".
The "greater detail" part can cost me a lot of time.
