Yes, It is viewScript and i am currently doing something like below in render.php but it is not ideal for large amount of attributes.

<div <?php echo get_block_wrapper_attributes(); ?> data-attributes='<?php echo json_encode($attributes); ?>'></div>

as for another approach there is something like below but it would not work properly for multiple blocks

<script type="application/json" id="block-attributes-json">
    <?php echo json_encode($attributes); ?>
</script>

I want some solution like i can pass some id and then fetch attributes using that id but using clientId is not ideal as whenever i load the edit screen clientId is going to be changed everytime.

Yes, These categories are compatible with GFAPI::get_forms();

You can access those categories like this

$form = GFAPI::get_form( 3 );
$form['gravityforms-categories']['gforms_categories'];

response would be an array of categories with bool true if they are assigned otherwise false like below

Array ( [7] => 0 [4] => 0 [5] => 1 [31] => 0 [32] => 0)
