I don’t believe there is a similar widely-supported dependency type in yum/rpm, though. rpm 4.12 adds support for Weak Dependencies, which have Recommends/Suggests-style semantics, but AFAIK it’s not going to be on most RPM machines (I haven’t checked most OSes yet, but IIRC it’s mostly a Fedora thing at this point?)
Which means in the rpm packages we’ll have to decide whether this is required or must be opt-in by end users (which as discussed would hurt adoption).
