Do we care? The main rationale for inventing a custom format, as I
recall it, was (a) plain text couldn't hack blobs and (b) you needed
the ability to rearrange the dump order to work around pg_dump's lack
of understanding of dependencies. (a) is a dead letter now and (b)
is much less compelling than it once was.
The custom format is still interesting in that it provides the option
to do selective reload --- but if that's what you want, dumping a
database at a time doesn't seem like a terrible restriction.
