Comment (by dmsnell):

 maybe these core filters should be registered as `add_action()` instead of
 `add_filter()`?

 > But I'm weary of Dennis' "additional caveat", because I can imagine a
 plugin rendering a block almost like it would "normally" but maybe adding
 a data-xyz attribute to some HTML element...and expecting core to have
 output the styles it would normally do.

 I'm not following this, but I guess I misunderstood this whole thing
 myself in assuming `null` meant "no more block" - feels like double
 negatives here 😅

 so yeah, ignore that additional thing or maybe instead of `null ===
 $pre_render` it should be `'' === $pre_render` - all I meant to do was
 have Core skip any enqueued styles if the block has been removed.
