Not editing the page for this because I think this is still sort of subjective and there's already a tag on the phrase, but I have a response to the tag where the article mentions "long term risks"
Having just completed the DLC's ending, I can say that there are technically long term risks to building around the monolith, but these risks aren't especially significant. After awakening the monolith to Tier 4, a small group of metalhorrors will spawn around it; this is the only danger I have encountered. Considering that during the event leading up to this, metalhorrors spawn across the map near void structures in greater numbers, including inside your base (presumably if unroofed and/or unlit?), and because this will only happen a single time right before the ending where you will be well-equipped to deal with a small group of metalhorrors, I don't think the risks are too worrisome, and it's certainly not a consistent danger.
