Certainly the Raspberry Pi OS (closely based on Debian, formerly

The issue (for those machines that have it) is not the OS: it's the
firmware (artist formerly known as BIOS). If that does not support
headless, it doesn't matter what the OS does, it won't reach the OS.
Agreed, but I thought my post implied that the Pi hardware was OK with
it.
I mention the OS in case an alternative (there are) did demand a
monitor. Both ends of HDMI certainly know whether the other end is
connected, many sources will not power up unless they see a live
sink, and sinks will usually not fully power the interface unless they
see something connected.
