No capitalization is not a tangential annoyance, it is a major complain akin to complaining about a text written in one block (without anything distinguishing sentences and paragraphs from each other).
i said sentences and paragraphs not words not having punctuation is absolutely akin to not capitalizing after all new lines and dots are designed and are working together and in unison to when combined convey the important information information of separation of pieces of information ways of compartmentalization if anything capitalized words are more visible than dots
