 While it doesn't specifically handle caching, the existing of a
 `parse_blocks` filter would make it straightforward to implement, as well
 as provide a pathway to solve the issue that prompted this ticket - Core
 does a lot of attribute manipulation when it's rendering (more so with
 Block Supports), so if you need to get those attributes programmatically
 there's no choice but to hit render_blocks() again. And if those _arent_
 cached, then it's not just a performance issue; you also have to deal with
 things like static `wp_unique_(prefixed)_id()` and other "fun" issues with
 layout styles, modals, etc.
