Honestly at the scale Joe is working at, the PRT isn't that exactly his major concern. He's concerned about everything, every organization, every parahuman's reaction to his reveal. He's not just concerned about the Triumvirate, but he's concerned about the CUI. He's concerned about the Elite. He's concerned about Gessellschaft.
He's concerned whether Phir Se would be driven into well intentioned panic and do something with his portals. He's concerned whether some hitherto parahuman unknown to the public would consider Apeiron revealing himself as unfettered to be so apocalyptic that they might as well go down burning everything around them. And yes, he's concerned if the PRT collapses on itself then there would be people crushed under the long unstable skyscraper that is parahuman regulations.
That's the scale of Joe's concerns, the scale of his standards. Every death or casualty that his reveal may indirectly cause that could otherwise have been prevented if he was more cautious, more perfect at how he could've done it is something that he refuses. You could even call it arrogance of the highest degree, but Joe is literally more and more godlike and near omnipotent as time goes by. Not only that, he has friends and allies that are ridiculously powerful in their own way. Logically speaking, if there's anyone who could manage it, it's them the Celestial Forge.
