You can't do one-line up/down scripts, but you could create a separate
service file and have it depend on the wg interface...

If you're using systemd-networkd to configure the rest of your
networking, having wireguard configured the same way can be useful; and
systemd-networkd can manage dependencies between interfaces as well (to
a certain extent).

However, as you note, things like running arbitrary scripts is a bit
more of a hassle...
