# Initially, our module depends on split-incompatible v2.1.0-pre+incompatible,
# from which an imported package has been removed (and relocated to the nested
# split-incompatible/subpkg module). modload.QueryPattern will suggest
# split-incompatible v2.0.0+incompatible, which we cannot use (because it would
# be an implicit downgrade), and split-incompatible/subpkg v0.1.0, which we
# *should* use.
