The current situation on the topic/libsolv branch is the following.
Suppose A requires B and the user asks to uninstall B. They will get a
problem report showing two possible solutions:
1. Uninstall A.
2. (default) Don't uninstall B.
If they uncheck 'Accept default solutions' and select 'Next', they'll
get a warning that says "We strongly recommend that you accept the
default solutions. Some packages may not work properly if you don't.
Are you sure you want to proceed?"
This is misleading insofar as it implies that something bad will happen
if the user prefers to solve the problem by uninstalling A. What is
true is that some packages may not work properly if the user answers 'Yes'.
I think we should be able to find wording that is accurate while still
making it clear that we recommend going back and fixing the problem. I
don't yet have a good candidate for that wording.
