Comment (by Bernhard Reiter):

 We recently landed [https://github.com/WordPress/gutenberg/pull/71483 this
 PR] which saves an Image block's `<figcaption>` as part of the block
 markup if its `caption` attribute is bound to a block bindings source.
 (Conversely, if the attribute is empty and isn't bound, the `<figcaption>`
 won't be included in the markup.)

 This still leaves us with the case where the block bindings source returns
 an empty value for `caption`, in which case the `<figcaption>` should be
 removed prior to rendering.

 Based on the discussion on this ticket and some conversations with @gziolo
 and @cbravobernal, we're now thinking that this should be the individual
 block's responsibility. This seems like a reasonable requirement,
 especially since a "generic" solution at WP Core level that removes those
 elements based on some criteria seems too fragile and error-prone (unless
 enabled by a special placeholder syntax, which would also come at a cost).
