Hours after posting my rant, I saw a CDC notice that seems to admit THEY KNOW. The article is couched in some both-and terminology, like they're burying the lede and hoping that nobody notices, but if you're looking for it then it's alarming.

"COVID-19 is likely to increase the risk for pulmonary aspergillosis and mucormycosis because of COVID-19–induced immune dysregulation and treatments for COVID-19 (eg, corticosteroids) that weaken host immune defenses against molds."

Opportunistic infection along with covid due to "immune dysregulation"? Yep. Where have we heard that before, I wonder? I expect to hear more of "undetectable levels" of virus soon too. I really hope I'm wrong and just being tinfoil-hat paranoid. :(
