Yes, though that comes with its own headaches since the data those sandboxed applications are supposed to touch are the only actually valuable data on my computer. (How many versions of OpenSSL are currently running on my Silverblue system? I literally couldn't tell you.) My spreadsheet is only vouched for by some random dude on Flathub and it can steal all my financial information. But at least it can't add a printer, or delete a system file that I can freely download from the Internet at any time.
