--- Comment #1 from Vladimir Panteleev <dlang-bugzilla at thecybershadow.net> ---
Workaround is to list all of the imported module's symbols in the public
import:

deprecated public import pub : someSymbol;

As a bonus that locks the publicly imported symbol list, so new additions to
pub won't be usable via the public import, even to users of -d.
