We can't support it in 1.x.  The SL code breaks when you run it multiple times.

Not convinced it would be that hard to support for the new code since
the output code is centralized, but not sure that is really that
helpful and some SL code has been wired into the new output code, so
that is a recipe for a mess.

Once 1.3 hits RC status, however, I'd like to start an open discussion
on the future of 1.x and possible beginning work on 2.x.  This would
be a great time to consider this.
