--- Comment #2 from Pierre Lemieux <pal@sandflow.com> ---
Right. This is not about avoiding taxing UA resources, but rather giving a
chance to the UA to avoid audible artifacts at splice points unless necessary
-- the UA can always ignore the flag.

When processing audio splices in the baseband domain (whether from native
baseband signals or obtained from coded signals), the UA will need to introduce
a fade of some sort (which can be audible if there is energy) unless it is told
that the audio signal is identical on each side of the splice.

The purpose of the continuousSplice flag would be to signal to the UA that the
audio signal is identical on each side of the splice. The UA could try to
determine on its own whether the signals are identical, but then we would need
to define what "identical" means.
