No. If I gather properly, the consensus was to use D[n] :-)
In any case, given new symbolics uses D derivative internally,
we need a conversion method between these two formats.
Unfortunately, the conversion is not one-to-one.
Consequently, integral (using maxima) that used work
in sage 3.4 doesn't work anymore. For example:
-----------
sage: var('x,a'); f(x) = function('f',x)
sage: g = f(x-a).diff(x)
sage: integrate(g, x)
-----------
doesn't work in new symbolics.
