I agree.

BTW this means the file dialog doesn't need to change the cursor, even 
QDialog::accept() is not a heavy action, compared to a file manager starting
an application.

So basically only dolphin needs to implement the pointing hand cursor (no 
option needed), the existing code you found (digikam, gwenview etc.) can stay 
but should just be cleaned up of the if()s, the kcm checkbox should be 
removed, and the kglobalsettings method deprecated.
