I like the idea of separating block chaining and basic block syntax.
That way, you don't need to pay the full price of the former if you only
use the latter.
However, filtering per language and headline header may be a burden. For
example, this ignores blocks before first heading, and forces user to
store them under the same headline. We could also keep :noweb-ref
references and chain all blocks with a given :noweb-ref, with a special
command. What about <<chain(..ref..)>> ?
Eventually we could add into the manual how a chained block can be
evaluated, since <<chain()>> is not meaningful.
WDYT?
