I'm not being rhetoric here - I am simply stating a fact. I chose my
words carefully and added "...in the past", because it may indeed
change.

That fact is not relevant to this discussion, though, because there
will always be a need to convert between formats. TTML <-> WebVTT is
just one format conversion that is needed. I simply chose an example
of something that people need to do today for some browsers if they
want to make use of native caption format rendering capabilities of
browsers.

Silvia.
