As discussed, it's a bit strange to delegate legacy input service to new input service which delegates back to the legacy input service on iOS/web. But if it's deemed necessary, then ok.

@m-sasha , not exactly. The MR basically drops usage of the PlatformTextInputService API and redirects calls to the new PlatformTextInputSession API. PlatformTextInputService won't be used anymore for all targets and can be removed. I have to discuss this change with @igordmn.

lgtm too

However, it breaks keyboard behavior

val keyboard = LocalSoftwareKeyboardController.current
keyboard?.hide()

This code does nothing in your implementation, probably something is missing from the old realization.

@mazunin-v-jb , thanks for checking. Fixed.
