WPDefinedAsset doesn't implemented for CSS files referenced in block.json

[ericestes]

• Part of Block API #41236.

Description

A handy feature of @wordpress/scripts is that it generates filename.asset.php files with automated file versioning for cache busting. However this only seems to work for JavaScript files (both automatically via @wordpress/scripts and manually via adding PHP asset files for CSS files).

Is this correct/intended behavior? Is there a way to get automatic versioning for CSS files?

Step-by-step reproduction instructions

Given a style.css file, an adjacent style.asset.php file, and a "style": "file:./style.css" property in block.json, the php asset file is not honored.
