No, it is the Linux OOM handler, which does not care or know about
what a Wayland window is.
If your daemon is invoked as a systemd service, you can adjust the
OOMScore in the system .service file of the daemon, like this:

  [Service]
  ExecStart=/usr/sbin/mydaemon
  OOMScoreAdjust=-250

The lower the value the less likely the process will be selected by
the OOM killer.
However, if you want to remain harbour-compatible, you cannot run the
daemon as a systemd service. In that case maybe you can write the
score directly at runtime to

  /proc/<your process pid>/oom_score_adj

but I did not test that solution.
