Add Grand Chess not Seirawan Chess

Recently lichess admin. has said that they are considering the adding of Seirawan Chess. ( https://en.wikipedia.org/wiki/Seirawan_chess )

But I think that they should instead consider adding Grand Chess ( https://en.wikipedia.org/wiki/Grand_Chess ).
First some similarities- they both add the same two pieces (R+N) and (B+N), they both have a good following relative to other chess variants,
The reasons why I think Grand Chess should be added instead of Seirawan Chess- 3 superpieces RN, BN, and Q add too much power for an 8x8 board causing an overly tactical, crowded game with too many exchanges taking place, Grand Chess will please more people because not only does it add more pieces, it also increases the size of the board, Grand Chess is an older game that has received more high-level playtesting unlike S-Chess which may have inelegant imbalances in opening play.

What about casablanca chess

Which admin said that? Cool!

Most players find Grand Chess to be an improvement over capablanca chess.

@kocbftn oh ok I imagine grand chess in 1 0 ultra bullet lol

I actually have physical grand chess pieces + board, and although it's pretty interesting, I would still want to see the implementation of Seirawan Chess more.

+1 Seirawan

What is the difference?

Ok grand is 10×10
Seirawan is 8×8
.

Seirawan chess is more interesting. It's not a symmetrical game as the two new pieces can be placed on different squares than you opponent placed them. Also the knight would lose too much of its worth on the 10x10 board.

Also the variant has a greater name.

I'd imagine for any variants that might be added, a standard 8x8 board would be preferable - less things to change when coding for it. There is no way that Seirawan chess has anywhere near the imbalance from the opening than Atomic, Anti-chess or Horde; at a guess I'd imagine it's pretty equal for both sides.
