(some good reasons for using separates)
...
(c) a separate can have its own with clauses, so this provides a way to
reduce the visibility of rarely used components. (After all, a good rule to
follow is to limit everything to the smallest scope where it is needed.)

(d) Most compilers really do compile these things separately. In a large
unit with frequent changes, this can save a lot of time. (Although that was
much more true when PC's were 4 MHZ, not the 4 GHZ that they are today. On
the IBM PC, the average compilation with Janus/Ada took over 10 seconds, and
long units could take much longer...)
