can any of the smarty devs indicate whether is any intention at all
of supporting this 'dereferenced' syntax? (possibly in whatever smarty3
becomes).

I for one would very much welcome it... but I also understand that
there are plenty of people, including the smarty devs that don't see
this as:

a, a priority
b, desirable in a templating system primariliy deisgned as a tool to
enable ['less' technical] graphic designers to better to their work.
