It seems that my fleet units have been running after I switched to OpenResty as a dynamic routing unit. It might cause I revmoved Requires or changed to Wants derective. By the way, it is very difficult to understand of systemd units behaviour coupled with etcd and fleet. In a Unit section there are some directives related to dependencies and ordering. I confused differences between effectiveness, so I collect some references for study.
