In which case it should install grub with a pre-awareness of other OSes
present.

Of course, one day an upgrade will be done, update-grub will be run
without os-prober, and any other OS will disappear... that sounds like
something Microsoft would do.

Surely during installation, a check for other OSes should be performed,
and if any are found then os-prober should be installed *and* *enabled*
by default, as it will be needed during every subsequent update-grub. My
sid just had its os-prober disabled by an 'upgrade', and I needed to
tweak the grub defaults to get it back.

Linux used to be promoted on the basis that it could be installed in a
Windows system for evaluation if there was enough spare drive space,
without affecting the Windows installation. It's hardly reasonable to
expect a newcomer to Linux, having apparently lost his Windows
installation, to research and install os-prober to get it back. The
most clueful will simply run a Windows boot repair and forget about
'that damned Linux'.
