GRUB doesn't depend on os-prober, it only recommends it.
One obvious effect is that when installing GRUB, other operating systems
are not necessarily detected. This was reported in #563204. However,
debian-installer includes a fallback procedure to write a static
/etc/grub.d/30_otheros in that case (for example, when installing from a
netinst without a mirror). This itself has a downside - if os-prober is
later installed, both 30_otheros and 30_os-prober will cause the
addition of entries for other OS-es, so other operating systems will be
duplicated.
One less obvious and worst effect, which was alluded to in comments of
#563204, is that the removal of os-prober eventually causes the loss of
other operating systems. And this is both likely and non-trivial to "debug".
os-prober is only extra. Its extended description reads:
This package detects other OSes available on a system and outputs the
results in a generic machine-readable format.
Unless the administrator reading this is very alert, it's unlikely he
will think the removal of os-prober can affect GRUB. And when removing
os-prober, there is no warning at all about an effect on GRUB.
Also, the effect will only be seen after grub.cfg is updated and then
the system rebooted, which will normally take days, usually weeks, so it
will be hard for the administrator to realize that his removal of
os-prober caused the problem when he notices the problem.
The duplication of menu entries could be solved by removing 30_otheros
when os-prober is installed. The loss of menu entries could be solved by
writing a "final" 30_otheros when os-prober is removed, in prerm.
However, it would be even better, and much less complicated to
implement, to simply make GRUB depend on os-prober, which only weighs
128 kB, as suggested in #563204. This would in fact allow a substantial
simplification of grub-installer eventually, and fix #650414 for free.
It could also make os-prober-udeb unneeded.

Hi,
similar to the installation-reports bugs, I'm closing the grub-installer
reports
below.
These are reports for Debian 4 / 6 / 7 / 9 where grub-installer fails (for
various reasons).
There have been numerous changes/improvements on this topics in the past, and
also because of the age of the reports we should consider these problems as
being fixed (or it is even reported in the bugs that they are fixed).
They are most likely of no use anymore for recent releases.
If you know, that the issue you reported (and gets closed here) is still
existing in recent installation images, please file a new report for that with
up-to-date details!
Thank you for filing these bug reports, they have been very useful at the time
they were filed!
