The trademark policy is low key important and I hope they are able to simplify the logo licensing at the same time.
The current logo is CC-BY-4.0 and almost nobody is giving Andrea Calabró the attribution required to use it legally.
https://github.com/godotengine/godot/blob/master/LOGO_LICENSE.txt
It being used as the default icon for new projects is problematic, lots of starting devs will publish their code or distribute their build with that logo and if they don't call out the logo licensing specifically its a license violation.
From a practical perspective I feel the default icon should be CC0, it would be a bit strange if that means we can't use the Godot logo but ¯\_(ツ)_/¯
