Hi, just wanted to point out a minor issue: The kovarex process recipe still appears in the Factoriopedia when it is disabled. I think there ought to be some way to fix that with the new "hidden_in_factoriopedia" property, maybe like:

if cfg1.kovarex_off then
    data.raw.recipe["kovarex-enrichment-process"].hidden_in_factoriopedia = true
end

On a side note, you may like to know that the technology effect reset script is no longer needed in Factorio 2.0.7+, since it's now run by the game itself! (Just gotta remember to declare "base >= 2.0.7" as dependency if you make use of that, of course ;-))
