Yes, I always find these kinds of screenshot restrictions more of a friction than real security. After all, anyone can still take a photo of the screen, less convenient, but it bypasses the restriction entirely. I understand the goal is to prevent malware from taking screenshots, but true security should come from a better model, like customizable capabilities. If needed, add 2FA or some form of consent before allowing a screenshot: the solution should be smarter, not just restrictive.
On (version 47 of) Gnome/Wayland, any program can take a screenshot (by calling out to gnome-screenshot) but the screenshot is accompanied by a flashing of the screen to alert the user that it is happening.
Gnome probably attempts to restrict taking a screenshot without flashing the screen (and I'm currently trying to figure out how to bypass the restriction).
