Are you able to provide a bit more detail or a code example to test? Specifically, can you talk more about the conflicts you mentioned?

I tried to set a featured image like a required fields, some while ago I used this plugin https://wordpress.org/plugins/require-featured-image/.
But with Gutenberg I have problems.

This can be accomplished with #10649 although I don't know if that is the recommended way for designating fields to be required; also there doesn't appear to be documentation for it.

@bianqui149 were you able to accomplish your goal using the info @skorasaurus pointed to in #10649?

Closing since a note was provided that this can be accomplished with the post save locking feature added in #10649 and at least noted in the documentation at https://wordpress.org/gutenberg/handbook/designers-developers/developers/data/data-core-editor/#ispostsavinglocked
