If I am understanding the discussion, it sounds like astrophotography would be a great use case for the e-shutter. Is that the general consensus?

I worry about camera shake and the large impression count with astrophotography and mechanical shutter use.

Thanks!

Yes, I use e-shutter, not mechanical shutter, for both telescope prime focus photography (Moon and planets) and for tripod-mounted or drive-mounted deep sky photography.

I use the Canon Connect bluetooth app on my LG Android phone to remotely release the shutter.

For deep-sky photography, with the M6 Mark ii you can also re-purpose the 'focus bracketing' feature ---- with a manual focus lens it becomes a way to set the camera for a certain number of exposures to be taken one after another with no timed delay, and no need to worry about 'buffer limit.' Using focus bracketing, the camera writes each image to the card after the exposure, then takes the next one. This is great for doing many exposures for stacking deep-sky pictures.

Since low noise is very important for astrophotography, it is also usually best to shoot with RAW format, not the lossy CRAW format. CRAW images will have slightly more noise and artifacts in the deep shadows.
