It appears that for the next couple of Olympic cycles, the trend in women's gymnastics will be to connect bar releases. So the Tkatchev technique of not focusing on a specific kind of tap and just swinging up and sitting up and dropping on the other side will now be obsolete (because you can't swing out of it into anything else, aside from kipping). Coaches still teaching Tkatchevs that way will be following the buzzards. They've actually been doing so, ever since the bar distance was changed 20 years ago; yet many still teach the Tkatchev technique that was compatible with the bars in close.
The men's style of tapping encourages strong counter-rotation; and this is what Wade had introduced to Sonya when he started her off on Tkatchevs. Eventually, hers ended up being a kind of hybrid.
