100% agree. Using it to polish your sentences or fix small grammar/syntax issues is a great use case in my opinion. I specifically ask it not to completely rewrite or change my voice.
It can also double as a peer reviewer and point out potential counterarguments, so you can address them upfront.

And LLMs always do what you say, absolutely always, no issues there.
