@305pelusa, I don't purposely tense my abs during a StC; I feel them working. I don't do a lot of direct ab work, and one of the reasons I like these is that they provide a different kind of ab stimulus than my usual things: kettlebell windmills, swings, and military presses, and barbell deadlifts. I like the StC because I get a nice stretch for my tight shoulders and some good and different stimulus for my abs.
I won't argue with you about the risks of a StC, save to quote Rif and say it really doesn't demand a whole lot - it's a gymnastics movement that I can do without training it, so that's another thing I enjoy about it, that I can just decide to do one or a few whenever I feel like it.
As @Harald Motz has also observed earlier in this thread, I don't feel like I'm hanging on my shoulders. I just let out a little of the tension I'm carrying in order to get deeper, then come back up. I get that one can hang loosely by the shoulders doing these and therefore place one's shoulders at risk, but I don't think doing that is even in my physical vocabulary. I'm doing these as weighted mobility, the weight being my rather low bodyweight. All kidding aside, I am long torso-ed and chicken-legged, and there ain't much chance that a StC is going to hurt my shoulders. I could, BTW, say the same things about my barbell deadlifts - the strengths and weaknesses I've developed mean a too-heavy deadlift just sits on the ground for me, not that I'm going to hurt my back trying to pull it.
For whatever reasons, valid though they may be, the things you're concerned about in the StC aren't concerns for me.
