It allows you to configure each interface for each network in
individual files, which simplifies adding/removing/editing them
(or tailoring their permissions).
In addition, when using "source-directory"¹, you can leave all the
configuration files in place, and deactivate them by, say, adding
a disallowed character to their filenames, rather than having to
remove them.
More and more of the system configuration files are being split up
in this manner.
BTW, I would add that, though I have a reputation with the OP for
not recommending man pages, the paragraph in man interfaces
that's headed "INCLUDING OTHER FILES" should make it very clear
what the relationship is between the /e/n/interfaces file itself
and any files placed in the /e/n/interfaces.d/ directory.
¹ I think source-directory was the default with buster, looking
at the netinst ISO. But one of my first actions on any new
installation is to overwrite the networking files.
Cheers,
David.
