Can't see why anyone would be annoyed.
What you're defending is a bit like replacing all female TV hosts by men and then saying that nobody surely is against men on TV.
I am fascinated by a single person taking up the cause of “correcting” the language of others based off of their personal linguistic aesthetic preference.
I don’t see many people saying “I often have to stop at the words ‘comprised of’ and reevaluate the meaning of the sentence that I’m reading lest I completely misunderstand it.” This isn’t actually in practical service of clarity, it’s an exercise in preserving a sense of meaningful posterity — a deeply personal and sentimental endeavor despite what “reasons” one is able to elucidate.
This sentence contains a load-bearing “best”. The Wikipedia editor’s contention is that they have established the canonical “best”, and it is that contention that is being scrutinized.
This is correct. It is exactly the same amount of subjective as the word “best” normally holds. Since there has never been a reproducible measure of best-ness in any objective sense of anything linguistic, it’s squarely in the territory of subjectivity.
If by “best” you mean “understandable to virtually all readers” then “comprised of” and “composed of” are equally “best”
If best-ness is measured by something other than usefulness, then the person that decides the new set of weights with which to weigh best-ness is performing a personal and subjective act. “Orthodoxy to a standard of English as cited by me in context of the year x” does not automatically qualify something for extra best-ness points.
I will gladly entertain the issue of “comprised of” somehow lacking in accuracy with a person that is genuinely confused by its inclusion in a sentence.
(On a personal note, as a non-native speaker of English I've always found the phrase "comprised of" confusing. I infer the "directionality" based on context but am unsure how to use it correctly myself.)
