You seem to be *very* confused indeed. 1.14.2 did not even have working
configurable effects: it was all hardcoded in C at the client and server.
There were effect definitions in the ruleset files, but they were simply
ignored. In fact, you couldn't even reorder the buildings in
buildings.ruleset without breaking the game rules.

Effects are good for simple continuous effects. Which are a significant,
performance sensitive, part of the code base.

Events are good for discrete events which can have quite complex
dependencies (e.g. you get unit X and tech Y if you are the Chinese and
conquer cities A and B after 1300 AD or if you are the second to
discover technology Z). Declaring these sorts of dependencies in
anything but a high-level language like Lua would be a PITA.
