KMessageBox::Dangerous considered harmful ;)

[Stefan Monov]

Hi.
The KMessageBox::Dangerous flag makes a message box set its default button to 
the "safer" one, for example to Cancel rather than Delete. The idea is that 
asking for confirmation is not enough of a protection, so the user should 
also be shielded from pressing Enter accidentally.
Me, I never pressed Enter accidentally, but I've always appreciated the 
ability to do Shift+Del Enter. i.e. finger2+finger4 finger3. It's easy yet 
safe.

So I put forth my suggestion: let us deprecate KMessageBox::Dangerous and 
rid the main modules of it.

aseigo, you added the feature some years back (commit 232842), so I'd love to 
hear from you especially ;)

Bye,
Stefan.
