Ok, sounds like a nice compromise to me.
Also, I wonder if using subsections would be even better when adding other things to the decrypted section. I.e.,
.data..decrypted:
...
.data..decrypted.aux:
...
.data..decrypted.something_else:
and this way keep it still conceptually together by keeping the section namespace clean because we're putting it all under .decrypted's namespace.
Hmmm.
