I just checked the code, and it appears that the cost increase was replaced with a change in research speed, which effectively does the same.
EDIT: It appears that Spacer and higher techs are also considered to be industrial. This was the change when moving from A18 to 1.0
EDIT2: Added a setting to restore the vanilla behaviour of A18 and earlier. This is disabled by default, but can be enabled in the settings menu.
