Obviously, this negatively affects the usability of nether portals in mob farms, which (while mojang usually frowns on farming) is clearly the biggest benefit of the new functionality of mobs moving through portals. If hostile mobs can't move through portals without despawning in smp, adding that feature altogether was kind of moot, save for like, moving mooshroom cows around quicker or whatever.
I understand, but there is a strong inconsistency in how mobs moving through nether portals is handled.
SSP: Mobs move through the portal on one side, mobs waiting to greet you on the other side
SMP (when no one else is online): Same as above
SMP (when more than one person is online): Mobs move through the portal on one side, but do not greet you on the other because they've despawned.
This isn't necessarily a flaw in coding and everything is working as intended, but it is an obvious design oversight. Am I... wrong in thinking that?
