If you have Skeleton A have the same Arm Length, Spine Length, Leg Length etc as Skeleton B and the only difference is B has a tail, then yes it's not that bad because most of the animations will be transferrable, while you only have to account for making sure the tail animations work and don't get in the way.
If you have Skeleton A be a standard Human-looking skeleton, and Skeleton B is an Ogre type that has shorter legs, longer spine (lower center of gravity), longer arms, and wider hips, then the animation transfers might not work properly at all. The running animations might work, but not fit a character that has a lower center of gravity and might have too long of a stride. The mounting animations might work, but legs might end up clipping through most models or the waist position is off because of the altered hip proportions. And making that many tweaks is on the level of practically making new ones, if we're talking about completely different proportions.
The alternative is then adapting to an existing race of similar proportions, like we're seeing with Tuskar having new skeleton and animations that are supposedly based on Pandaren (from what I've heard, so I could be wrong). That is something that saves time.
Animation and technical work (making sure clothing works, making sure facial customizations work, etc) is where most of the iteration and time is spent.
Animation transfers is a common thing. We use it all the time for WC3 Reforged modding. Yet just because it works and is common doesn't mean it works for everything. For example, we transferred animations of Reforged's Dragons onto Heroes of the Storm Deathwing to give him Flight animations. The animations work, but they also get pretty F'd up. So yes, transferring would save time if the proportions of the two things being transferred are relatively similar. If not, they can actually waste more time than save.
