I recently discussed with upstream about packaging games in Debian and 
they got confused by this naming scheme, so I would +1 this.

This is also causing bad practice when packaging games, because the 
package will depend on godot3-server to perform -headless tasks such as 
generating .pck files (instead of godot3-headless), see e.g.:
https://lists.debian.org/debian-devel-games/2021/02/msg00013.html

If it's inconvenient to provider yet another build, maybe we can use 
Provide:s.


FTR their terminology is:
https://godotengine.org/download/server

* "The _headless_ build includes the editor tool functionality that 
enables it to run tests and export projects in an automated manner."

* "The _server_ build is optimized to run dedicated game servers and 
does not include editor tools, graphics or audio support."

Cheers!
