ETTR is an exposure solution to the problem of lack of shadow recovery in Canon sensors. Its not needed on Sony based sensors which have fantastic shadow recovery ability without a noise penalty.

Canon sensors typically are good with highlights but poor with shadows hence ETTR so the shadows are brought up and you use the highlight headroom to do so.

In my experience the X trans is more prone to blow the highlights a little but have great shadow recovery so I think it would be a poor strategy on an X camera.

Strictly speaking, ETTR is not about "shadow recovery". It's only hallmark is that the important highlights are exposed just below the saturation level of the sensor.

For scenes with low dynamic range, ETTR usually results in images that are too bright compared to the scene brightness. A side benefit is that shadow regions will get a boost in signal-to-noise.

For scenes with high dynamic range, ETTR usually results in images that are too dark compared to the scene brightness. In this case, the shadow regions will suffer, but - as you say - one might be able to adjust them afterwards with good results. I am not so enthusiastic about this, though. I have many landscape scenes that have quite noisy shadow regions, so much so that printing at large sizes isn't really an option, despite the brighter regions having no visible noise at all.
