OK, that's exactly the kind of feedback I've wanted to get. But as such 
constraints are not common (or they are?), I still think that this should be 
(and easier to) implemented in opt-out fashion. So, I'll try to cook up a 
patch today that does 

RRECOMMENDS_${PN} += "${PN}-logrotate"
RSUGGESTS_${PN}-logrotate += "logrotate"

and then add some "PURGE_LOGROTATE" variable that will trigger *-logrotate 
packages removal from image if there is a need to.
