I think if the conversion is led by a very experienced React developer this could be a good decision. We decided to write all our sites in React a long time ago and couldn't be happier. It doesn't have to be a SPA because it's React, we have static sites too. Judging by how your org made the decision without the devs input though, I'm not too confident it won't be disaster. It's depressing but I've been offered too many contracting opportunities to rescue a project after a similar conversion that is a total dumpster fire.
