For security reasons, I support it for any kind of government work that involves data you wouldn't want to fall into the wrong hands. I have a couple of family members who do high security clearance government stuff, and during a family emergency, they were using my room as an office to do remote work, and i assume they were using my normal civilian wifi as well.
If i was a spy in that situation, i could have stolen important info without any computer hackery being involved. I shouldn't even have that opportunity.
Ive also had problems with hacker neighbors in the past gaining full control of our network and computers, so i learned firsthand that nothing wireless is actually secure unless you are in a special room with signal blocking walls and stuff. Even then, you can never allow any outside devices to connect to anything inside the protected area (the network itself, phones, wireless headphones, etc).
They've been doing remote work since covid, and this change has been a major pain in the ass for them, but imo its for the best.
