I agree. It must be applied. This is why I suggested creating a user
script that makes use of the parser and adds media fragments support
to any website.

True, too. The better the parser, the easier the player implementors'
lives. Things can still go wrong, though, but of course in general the
parser quality is reflected in the player tests. The more players we
have, the more chance that something wrong gets detected in the
parser, though. Each player still has to cater for the low-level stuff
like checking whether a spatial fragment is applicable given the
video's resolution etc.

Best,
Tom
