Blacklisting professions: is it possible?

[BorkBorkGoesTheCode]

@BorkBorkGoesTheCode

The mod series I currently have planned will allow a player to create a world set in any decade between the current default era and the year 1800 AD, but I may expand the series to include every year within that time. The first mods will be set in the present: From there, I plan to make a mod for the 1980’s, followed by the 1960’s.

I want to remove professions that rely on future tech, such as the bionic professions, from any of the game starts that use my mod, without removing the professions from the main game.
