Before wasn't just Yak Track + a major update, it was the first Yak Track, Farming 120 + Ranch Out of Time, Herblore 120 AND DXP weekend all in quick succession. This is a little different and should not be anywhere near as overwhelming.
There's plenty of time to complete the Yak Track for one, and for parts of it you can progress it by playing the new skill, so the synergy should be better and the stress a lot lower.
If it still proves too overwhelming for some, I'm sure that will be taken into consideration for future Yak Tracks.
