If they do that, Mozilla will probably immediately update the check or remove it all together.
I don't understand why systems administrators don't just use their existing policy management to disable DoH if it really causes an issue. There's a group policy specifically for DNS over HTTPS [1]
The only reason I can think of is that they can't because of BYOD or Firefox being part of the company's dark IT. The DNS workaround doesn't help much in those cases because the underlying problem is a lack of oversight, not an issue with Firefox.
