Arno's Engram Keyboard Layouts

Some explanation of the design principles would be welcomed. The workman (https://workmanlayout.org/#introduction ) website is really interesting in this regard, even if you disagree with the end product. [As an aside, the Svaalboard has been my saviour, that and a ludicrous amount of QMK customisation with tap-dance functionality.]

"Engram is a family of keyboard layouts optimized for comfortable and efficient touch typing in different languages created by Arno Klein. You can use the open-source software to create new key layouts optimized for different languages."

Why would the center two cols be used for such low probability symbols.

The braces being so far and tucked away make it really bad for c like languages

I looked at the repo but I didn't see anything about the design principles. How does this compare to Colemak-dh on things like inward rolls and SBFs etc ...?

For some people, a layout which spares the pinkies is preferable. The BEAKL layouts, for example, are optimized using a hand model which keeps the pinkies as idle as possible. Sometimes this can make all the difference.
