There isn’t a hidden meaning. It doesn’t say anything about what I think would be useful to you. My actions are generally mostly about me, not about you.
I thought it was more useful to say than nothing. But I didn’t want to say more because that would require more work.
Also, sometimes when I point out some errors but not others, people think (that I think that) there were no other errors. I wanted to avoid that potential misunderstanding.
None of these were hidden meanings of my sentence, which simply didn’t include this other information.
