That solves the actual issue at hand while also making SAM more interesting than either pre or post Kaiten removal.

It getting removed with no replacement is the only reason why its removal is a problem other than "I think it looked cool".
There were many discussions on this matter, but I have yet to see solid idea for a replacement. Problem is that it cannot be anything that would result in dps loss, so realistically, it would have to be higher damage than Shinten, while being locked by higher CD. But alas, that already exists, it's called Senei. Realistically, you could make something between Senei and Shinten, but you'll end up with 3 very similar skills, which sounds really uninteresting and bland. Kaiten simply fit perfectly into the Kenki management, it was made for it and was more interesting to use than just bland damage oGCD. That's job design reason, but satisfying animation and similar are also rightful reasons.

There's obviously more to this than just Kaiten, 6.1 had like 22 changes to SAM. Circle Tenka and guaranteed crits are also bad, but people just usually talk about Kaiten since it's biggest outlier. If you want to go more in depth, this whole topic has been discussed through and through in 100+ posts in DPS subforums already.
