I agree with you.

Although I believe HTML+JS+CSS achieve a declarative approach
to some extent without SMIL, I'm not sure it's the best solution for
signage industry.
The fact that some signage operators are using SMIL implies that
there must be some advantages for creating signage contents.
So, I think that we shouldn't reject SMIL out of hand for now, too.

Yes, it depends on.
Regarding the requirement "A declarative approach",
we have not yet found any concrete gaps between the requirements
and existing open standards for now.
So we don't need to change existing standards nor to create
new standards for now.
But if we will find any concrete gaps in future, then we will need to.

I think so, too.

I started to learn SMIL, I think the concept of SMIL is nice for
"A declarative approach".
Aside from whether we will support SMIL or not,
I think the concept is worthy consideration.
