Are you sure?
This is not the case in the latest iOS. Long-pressing the icons in Control Center offers a wider view and access to hotspot and airdrop settings. Pressing either WiFi or Bluetooth from this second menu has the same effect as the icons on the first page, (you can inspect settings afterwards and see it’s still “off until tomorrow”) and further long presses on the second page icons only let you choose which WiFi network or Bluetooth device to connect to.
On my phone (iOS 14.6), the Wifi and BT say "New Wi-Fi network connections have been turned off from Control Center" after long press. But that _seems_ to be the same message as if I do the "until tomorrow" way.
And the actual Wi-Fi and Bluetooth sliders are decidedly in the ON position. I must've concluded that since it didn't do the "until tomorrow" message then it behaved as I wanted.
In general, try long-pressing everything: there's generally shortcuts or "power moves" afterwards.
