Comment (by westonruter):

 Also as I [https://core.trac.wordpress.org/ticket/63007#comment:8
 commented] on #63007:

 > I think a better approach for inlining classic themes' `blocks.css`
 would be to split up the stylesheet into multiple stylesheets, one for
 each block. Then if we can enable `should_load_separate_core_block_assets`
 for classic themes, then we can only enqueue the specific theme block
 styles which are actually used via `wp_enqueue_block_style()`. This would
 require the use of output buffering from #43258 (which I've just
 milestoned for 6.8), however, since we'd need to inject the CSS from the
 `head` after the rest of the template has been rendered. Maybe the themes'
 blocks stylesheets can't be split up so easily, however.
