soft-deps (Suggests/Recommends) is really hard to handle at the depsolver

decisions based on that, a asking the user every time is not a good solution
IMO. You will need to take a popquiz every time you what to install a
package.
I can see that the information can be useful at a high level gui or in some
kind of appstore. People there have bought 'foo' have also bought 'bar'. But
at the lowlevel like rpm/yum is not very useful, because we don't have the
needed infomation to make a good decision.
I wouldn't think it's that hard to implement. When installing a new
package, simply treat Suggests as Requires; when removing a package
just ignore Suggests completely. Only upgrading adds a little
complexity - if new version Suggests something that the old version
doesn't, treat it as Requires (so that I get new optional pony
accessories automatically), otherwise ignore it (so that I can throw
away that optional pink bracelet and not have it come back every time
I update).
Note that that would be horrible behaviour for also keeping a minimal
packageset.
