The guidelines given to users who are about to suggest an edit are (boldface mine):
Your edit will be placed in a queue until it is peer reviewed.
We welcome all constructive edits, but please make them substantial. Avoid trivial edits unless absolutely necessary.
The last sentence does not seem good guidance to me, no matter how I interpret the word trivial:
If I take trivial to mean with little value, the guideline is self-contradictory, because if something is absolutely necessary, it obviously has value.
If I take trivial to mean ordinary or not intellectually challenging, the statement at least makes sense, but would exclude, e.g., an edit that inserts paragraphs, capitalisation, and punctuation in a typical wall of textspeak – which I would consider tedious, but still trivial, and in particular a worthy edit.
Also, while I am at it: Why absolutely? If a wall of textspeak can still be read eventually, I would not consider it absolutely necessary to edit it, but still a reasonable edit.
Moreover, the versatility of meanings of the word trivial make this guidance prone to be misunderstood by somebody who is not that familiar with the English language.
Note that this is not a duplicate (but probably a result) of: Remove "unless absolutely necessary" from suggested edits text
