Why is this a new setting and not something you access through coreData canUser or something?

The main reason we started using a new setting was to allow users to disable this behavior with a PHP filter if wanted. And it seems there was a precedence for this with canLockBlocks: link.

It's true that user capabilities can also be modified through a filter, so if we are able to access edit_block_binding in the editor somehow, we wouldn't need an editor setting.

I couldn't find a way to do so, but I must say I'm not familiar with user capabilities.

I'm happy to explore other paths. Is it possible to access these user capabilities? From what I understood, canUser checks whether the user can perform the given action on the given REST resource. But that's not exactly what we need here.

Another possibility to replicate the capabilities mapping in JS, but I am not sure it makes sense and I believe users wouldn't be able to override this behavior easily.

Any thoughts are more than welcome.

There are a lot of precedents for block editor settings indeed. But IMO, we should start moving away from them like I explained on my recent blog posts about Gutenberg practices.

In this case, it's a capability check and we should just have a unique way to fetch capabilities from the client. I think @Mamaduka might know better whether that's already possible or not.

For clarity, I'm not saying that users shouldn't override the capability in php, I'm saying that the frontend should access the capability through the capability APIs and not block editor settings.

If we can make it work this way, I agree it seems the best path forward. I will take another look, but I couldn't find a way to do that, at least with the existing APIs.

I guess the difference with the global settings is that this endpoint is user specific. So maybe a "user settings" endpoint.

Writing that, I wonder if that's just the user endpoint though :P

If I'm not wrong, that endpoint has never made it into Core.

Yeah looks like it's still GB only. We should probably merge that, I can't remember any specific reasons why we held off on it.

I'm personally convinced this is not user preferences though.

I'm not too fussed if it's a "preference" or a "setting". But I do think it's not a capability.

I think we need a consistent global settings endpoint in Core.

Along the lines of wp-block-editor/v1/settings?

I know we used the "root" endpoint for that sometimes. Maybe we should just continue using that

I think this is less of an index type of thing, since it is so spceific to Block Editor UI, and not the general capabiliites of the site.

I don't think it would be odd, IMO, for wp-block-editor/v1/settings to take into account the user when building the settings. It's already something that I imagine extenders are using when filtering.

Just to be clear, I think a block editor settings endpoint would work here. But I wonder if it's a bit shortsighted in the sense that we'll have a need for similar settings (user settings) outside the block editor. (For instance, a setting to prevent users from creating custom WP-Admin views or a setting to prevent users from using "filters" in the different admin pages, or random things like that)...

Yeah we should start exploring that in more detail.
