yes; I've found this a missing feature occasionally myself.
If I remember properly, S' version built on the output of sabl()
whereas we'd need one building on stl() out --- if any at all.
As a matter of fact, I'd like a more general setup that does not
only work with periodicity 12.
monthplot() would then only be a compatibility wrapper calling
the more general function.

Note that Brian Ripley has recently added quite a few things to
`ts' in R-devel, including StructTS() for structured time-series
analysis which includes seasonality.
