Why is hostname not included in the default group for networking?

At line

docker-compose-linter/docs/rules/service-keys-order-rule.md

Line 88 in c49696e

**Properties order:** `ports`, `networks`, `network_mode`, `extra_hosts`

hostname is specifically excluded.

Why is that? I see that it is a deliberate choice since further down at

docker-compose-linter/docs/rules/service-keys-order-rule.md

Line 200 in c49696e

"hostnames",

you suggest how to put it in.
To me, since it belongs to the networking category, it should be so by default, no?
