This moves the problem only to the programmer/implementor.
How much is 'auto' and is this a textRate useful for the user?
I think, poor implementors are left alone with the problem, how
to determine a sufficient textRate if only 'auto' is possible and
values in px are not useful for authors/users as already explained.

A better approach was already provided in the original comment.
A better solution for authors with this problem might be to use
SVG (animation and defining font-size; zooming for users) 
instead of SMIL to avoid the problem (not perfect, but maybe 
a more advanced and flexible approach).
