Not really, it's more accurate to say that no one had tried to figure out an 
alternative with the needed semantics. That didn't happen until the GNAT 
people invented source-based translation for Ada (since copied by some other 
compilers).

In any case, Janus/Ada uses a "library", really mostly a set of already 
compiled files. (It imports already-compiled symboltables, it doesn't try to 
recreate them each time. This is complex enough that it doesn't provide any 
significant advantage over the source-based alternative.)
