I believe https://github.com/WordPress/gutenberg/pull/28088 makes it so that template files are always assumed to be from the currently active theme. This makes the theme attribute on <!-- wp:template /--> and <!--wp:template-part /--> obsolete, and could become an error depending on how it's resolved.
We should update TT1 Blocks to remove the theme attribute for clarity.
