I don't understand the argument.

Because... choosing a lower (and simpler) layer of abstraction would mean that
less code would need to be reimplemented?

As I understand it, every time DMD implements a new expression type (for
example, dot multiply), GDC and LDC would need to be updated. However, DMD
already has a glue layer that lowers all of the D-specific expressions to
something closer to abstract machine code, which I'd think is what alternative
backends would be more interested in.
