How would we know that? Here's a novel idea - Unless there's a pressing need to change to 1x right now just ride only the 42 tooth for a while and see if it restricts you. Frankly, I don't see the attraction of losing a chainwheel. It's hard to believe that a front derailleur would be very problematic on a bike in that price range, and what you gain in simplicity you lose in extra wear, as you will be riding the small cogs more than before and wearing a single chainring instead of two.
