My proposal was rejected, and a different proposal by Michael Everson (http://www.unicode.org/L2/L2016/16270-n4766-xiangqi.pdf) to encode all circled ideographs and negative circled ideographs attested in Xiangqi game diagrams was accepted instead.
Not quite. At the WG2 meeting it was proposed, I believe by experts from the US, to use circled ideographs to represent xiangqi characters. “In for a penny, in for a pound,” I thought, and so said that if we were to do that we’d have to encoded all the attested circled ideographs, because you can’t have a circled 士 (58EB) and say that a circled 仕 (4ED5) is a valid glyph variant of it. Then I wrote that proposal so that we could have an actionable document with which to get characters on the ballot.

This is true.

It makes the interchange of Xiangqi game data and game diagrams problematic; it hinders normal text processing operations on Xiangqi game pieces (for example, to search for a red horse piece you have to search for three different characters);
Yes, it does. It is important to remember that this use of symbols is a text usage.

Or black and white designs showing for instance an actual elephant rather than 象 8C61.

I was convinced, and my proposal to rectify this were provided as Irish ballot comments to PDAM 1.2.
