I'm wondering if there is standard advice on debugging build failures introduced by setting implicit_transitive_deps false? For example, I added that config to a project that includes a ppx rewriter and see:

Error: The module Selected_ast is an alias for module Ppxlib_ast__.Import.Selected_ast, which is missing

I suppose that by digging through the metadata files for ppxlib I would eventually find some library name to add to the stanza:

(library
 (name ppx_trace)
 (kind ppx_rewriter)
 (preprocess no_preprocessing)
 (libraries ppxlib))

But is there a better message that dune can give, since without disabling implicit_transitive_deps the build succeeds?
