Some graphical greeters, such as gtkgreet and wlgreet, store various things in their home directory, such as the mesa shader cache. Having a home directory also doesn't hurt for greeters that don't make use of it. As an example, greeters using Wayland compositors will attempt to cache shaders in the $HOME/.cache/mesa_shader_cache directory. Also, greetd explicitly is designed to not really care about the greeter in use, so it doesn't make sense to NOT have a home directory for the greeter: the lack of one is making an assumption about the greeter run by greetd and serves little purpose (having an extra empty directory for greeters not making use of a home directory doesn't hurt). With regard to other distros, Debian also creates a home directory for their greetd user[1][2], as does Fedora[3].
