There are big difference between Tiny and Basic, so if their player is 
still in that range I would expect that they started with a Basic 
implementation and removed things instead of doing Tiny directly (but I 
could be wrong). That would likely result in larger sizes.

According to their website, they support Tiny, half of Basic, and some 
stuff from Full. So it would seem to be quite a bunch more than a Tiny 

You also want to note that eSVG is also a Basic implementation so using 
its numbers as a proof of SVG's size doesn't work either ;)

Yeah I know, I was simply quoting TinyLine as an example, and as I said 
I am unsure how representative it is both ways (it probably has more 
bugs than one would want, and the code doesn't seem to be optimised for 
mobile as aggressively as it could).

I have no idea how much it is tested, but I doubt it would be optional 
(can't find a place that would make it so). It would be a bit strange 
not to support that as one could then not animate several elements with 
a single animation. It's a bit like requiring transform to be on all 
elements instead of inherited.
