Hello,

I think, the specific behaviour of frozen to-animation is a key feature
of this specific animation type.
To change this makes the feature less useful, because it is difficult
or not possible to get the same effect with another method.
The proposed behaviour is available already, if no to-animation is
used, therefore if authors need this behaviour, they can simply use
values animations.

I think, the attempts (as for discrete animation) to change to-animations 
and the bugs in several current viewers indicates a general misconception of
such implementations to treat it as an ordinary animation.
One should note, that from-to-animations, from-by-animations and by-animations
are defined to be equivalent to specific values-animations. Therefore those 
animations are additional fun, not necessarily important, because one can
get the same effect with the equivalent values-animation 
(this approach works for set-animations as well).
to-animations are not equivalent and provide another feature, in parts
comparable with CSS-transitions. Because it is defined to be different to 
values-animations, it should be no surprise, that it behaves different and
needs a different implementation - this is the whole point about it ;o)
CSS spends a complete draft for such effects, therefore it should be possible 
at least to get to-animations implemented for SVG as specified ;o)
