Can ACF support the native render callback in block.json?

Hello @lgladdy,

I read about it here: https://github.com/WordPress/gutenberg/pull/42430

It seems that block.json supports a render callback by default.

src/block.json

{
    "name": "test/my-block",
    "render": "file:./render.php"
}

src/render.php

<div <?php echo get_block_wrapper_attributes(); ?>>
    <?php echo $attributes['text']; ?>
</div>

I'm wondering if we can use this render callback instead of ACF's own "renderTemplate": "index.php" in the future if ACF supports it?

Could this be a solution to make ACF block markup identical in editor and frontend? 👈 👈 👈

Have you ever been able to test whether this can replace the additional block wrapper?

Start by reviewing the referenced Gutenberg render callback behavior alongside src/block.json and src/render.php, then trace how ACF applies renderTemplate and its additional block wrapper. Determine whether native rendering could replace that path while keeping editor and frontend markup identical; done means a documented, tested decision.
