Agreed, Graphene is effectively running arbitrary enclave code.  I'm
guessing there is nothing that prevents extending/reworking Graphene to
allow generating the enclave ahead of time so as to avoid populating the
guts of the enclave at runtime, i.e. it's likely possible to run an
unmodified application in an enclave without EXECMEM if that's something
Graphene or its users really care about.
