Actually, nowadays there are most sophisticated technical solutions
which mount on a single click. No warning, no options.

Yeah...by clicking on that shiny 'optical disc drive' icon.

uuhhm f.e. ISO9660 right?

..other than the fact that windows doesn't have the concept of an
executable flag beyond the EXE extension. And wine as the linux
executable that is actually being run *does* have the +x bit set...
while i agree logically EXE files _should_ be flagged x aswell in
practice requiring the flag ties wine's functionability to close to
the randomness that is the user's choice of distrobution and its
default mount options. Starting to require +x from the next release on
is sure to break a lot of those systems.
