I fail to see the relationship between the statement and your question.

Again, whether or not the C API is frozen has nothing to do with
whether or not the bytecode format is frozen. So any implication
from not freezing the C API to not being able to ship byte-code
only is invalid.

As for only shipping byte code: sure, that is certainly possible,
and people do that all the time.
