that every other distibution calls it all the time "named" and "httpd"
and it's painful every time you toch a debian setup you have to remember
"apache" and "bind9"

what if bind10 wouldn't have failed and you get a software update after
some years?

what if httpd releases 3.0 ina few years besides that "apache" is
completly wrong to begin with becaus eit could be Apache Tomcat, Apache
Trafficserver, Apache Httpd

mainly that this is a distribution issue and when they are smart you can
type "systemctl reload named" and "systemctl reload bind9" without
confusing people which know it's named outside the debian world

Units can be aliased (have an alternative name), by creating a symlink
from the new name to the existing name in one of the unit search paths.
For example, systemd-networkd.service has the alias
dbus-org.freedesktop.network1.service, created during installation as a
symlink, so when systemd is asked through D-Bus to load
dbus-org.freedesktop.network1.service, it'll load
systemd-networkd.service. As another example, default.target — the
default system target started at boot — is commonly symlinked (aliased)
to either multi-user.target or graphical.target to select what is
started by default. Alias names may be used in commands like disable,
start, stop, status, and similar, and in all unit dependency directives,
including Wants=, Requires=, Before=, After=
