I mean there are a lots of feature is locked behid dlc feature flags but documentation seems not actually explain what mapped to what,only said it require space age.
For example what feature key is agriculture tower catgorized in? spoiling? how about plantprototype ?
fusion-reactor prototype?
is more Planet categorized in space_travel ? etc...
in a way
https://lua-api.factorio.com/latest/aux ... cture.html do explain something but not much...

If my memory serves me right yes, its just not been done yet afaik. You obviously can't rely on the space-age graphics for your own fusion prototypes then.

Actually you can, even if the space-age mod is disabled, you can actuallly use __base__/../space-age to load their graphics.

No, you can't
rely upon it. This will produce an Error for players
without the 
DLC.

I will do some testing, but for now I do have a idea to detect if space-age exist while being disabled

Answer: No, because helpers.is_valid_sprite_path("__base__/../space-age/thumbnail.png") is not usable in prototype stage.
and even it does, you probablly cannot use it for detection purpose at all.

To be fair, being able to do that's a sandbox violation and should be fixed (
or made properly a feature).
