Microsoft has also added "suggested phrasing", which prioritizes concision even when it removes deliberately inserted uncertainty. In some cases, following its suggestions wouldn't even have resulted in coherent sentences. For a sentence of the form "Do $X, unless $VAR is true." had the recommend replacement "Do $X, unless $VAR.".

Was your actual sentence "Do $activity, unless $condition is true." (with $activity as say 'print the annual report' and $condition as 'Steve has printed it')? I'm struggling to see how the result wasn't coherent. Something like "Do P&L, unless Wednesday" is terse, but not hard to parse; I must be missing something?
I tried to look back to find the exact example, but couldn't find anywhere that I had written it down. It was something where the $condition was a single word, referring to a boolean variable, but was not itself an adjective. By removing the "is true" clause, the clause was left without a verb, and without an antecedent.
