I missed this discussion; why was it discouraged?

I can think of some reasons why I guess.  But I don't see what
problem comes from linking together a "mega module" that's made
up of well-isolated source files that expose minimal APIs to
one another.  All inter-dependent modules will required at once
anyway; I don't understand the benefit of implementing them
separately.  Can you explain, or provide some context?  Thanks.
