--- Comment #5 from sworddragon2 at aol.com ---
I'm using a minimalistic system and have disabled at default the installation
of recommended packages in apt. Also I think this topic can be extended to more
packages as for example if libxcursor1 is missing mouse cursors are not being
rendered correctly and if libxi6 is missing raw input does not work.

Some reasons why I think a reconsideration what should be a dependency and what
should be a recommendation is needed:

- Ubuntu installs at default recommended packages so in this case it would not
make an effective difference if the packages would be a dependency or a
recommendation. But the few users that do not install recommended packages at
default will notice earlier or later issues on normal usage.
- From the debian policy about Depends: "The Depends field should be used if
the depended-on package is required for the depending package to provide a
significant amount of functionality.". Sine Wine provides the Windows API for
non-Windows systems a working mouse and working PNG-support are in my opinion
indeed significant.
- Even if the installaion of recommended packages is not disabled apt does not
always guarantee that they are getting installed. I have reported this already
here ( https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1571363 ) but it is
not known if this is intended or just a bug. At least this is how apt handles
this now for several years or even more. The 3 packages used as example here
are also affected by this behavior and may not get installed even on executing
"apt-get install winehq-devel --install-recommends". How much this affects a
real system may depend how long the installation exists/how often the package
state got changed. Over time systems might end up with the one or other
recommended package missing causing eventually the user to notice an issue and
creating a bogus report.
