I agree, no need to go to the personal level. But technical
discussions have to be done publicly whenever possible, to make sure
all that have an opinion can express in time. (the recent problem with
StereoMode changes is a good example of something that could have been
avoided with more public talks)

Yes, I will change the specs to make sure it's clear that padding
after SeekHead is recommended (even for things that don't even exist
yet in Matroska).

I'd rather keep it as synchronized, because that's the best way to use
it. One thing I hate is when the same information is found twice in a
file. Because if one is changed, the other is unlikely to be fixed.
Plus it takes more space. Same reason why I prefer cover art in one
place and not 2 possible (and since cover art is already common as
attachment, that mode has to prevail). But for lyrics I guess it could
be put in tags too, because adding the syncrhonisation info is a lot
of work and will never happen in basic tag editors. So I will add an
"entity" in the tags specification.
