The two reasons are:

1. IME passing an font name in the :font attribute gives in general better 
results than passing a font name in the :family attribute.  (And Dmitry 
confirmed that the problem he was facing was mostly solved with that 
change.)

2. Dmitry's specific recipe, which worked with Emacs 28, cannot work 
anymore with Emacs 29 because of dae3c4e89b.
