It is not enough. Static library symbols are not exported, if they
are not used. Linker drops them. It means almost all needed symbols
are removed when you just remove the option.

Alternative is to use option all_load on clang (and whole-archive on
gcc), but that exports *all* symbols and *all* functions. Even the
ones which really are not needed, but are just a part of some library,
which we don't want to trim.

The decision was made to go for the former option.
