A game from 1937 between musical luminaries Sergei Prokofiev and David Oistrakh reached the following position after 11. Be3-h6.
Black played 11...Rg8 and had difficulties but eventually drew. Several kibitzers at https://www.chessgames.com/perl/chessgame?gid=1266497 thought that 11...O-O was better. My gut reaction was that castling kingside would make the coming advance of White's h-pawn even more dangerous, and I doubted that Black could survive. But it turns out not to be so simple, and I spent untold hours on how to overcome Black's various defensive tries.
A likely continuation through White's 16th move is given in the following chess movie.

O-O-O, and White will soon play f4... to open the kingside.} 12...Bxh6 13. Qxh6 f6 14. h5 g5 15. f4 {If now 15...gxf4 16. Qxf4 e5, then 17. Qg3+ defangs the fork and leaves Black with many weaknesses.} 15...e5 {To try to induce 16. fxe5 dxe5, so that the kingside would be mostly closed and Black would have gained space there.} 16. Nf3 {If now 16...Bg4 17. fxg5 Bxf3 (Intending to answer 18. gxf3 by 18...fxg5.), then 18. g6 Qe7 19. gxf3 would leave Black a pawn down and still subject to attack.}
In the position reached at the end of the above chess movie,
Black's g-pawn is threatened, and 16...g4 would seem inadequate after 17. Nh4 (threatening to strand Black's g-pawn by playing 18. f5 or to saddle Black with a backward pawn on a half-open file by playing 18. fxe5). The critical lines seem to start with Black's capturing the f-pawn, and the next two chess movies examine 16...exf4 and 16...gxf4, in that order.

Conclusion
Had Black played 11...O-O, then 12. h4 would have given White a clear advantage. So, I'm not sure that 11...O-O would have improved over the game's 11...Rg8.
