Back to the moon, only CEV reuseable?

Looking at the planned vehicles for the return to the moon, the
article(s) seemed to emphasize leverage of shuttle technology. For
example the use of SSMEs and SSRBs. However, only the CEV was described
as reusable.

Will the new systems also recover and reuse the boosters? If not, seems
like a waste of a good SSME which are supposed to be good for many firings.
