Options are always cool.
I just to say a few brief things about that, because this sentiment comes up a lot, and from a development point of view, I strongly disagree - though not necessarily in relation to this particular suggestion.
Yeah, options are nice to have for some things. They can also seriously increase the amount of testing required to make sure everything works right - especially if some of the options interact with each other. They add extra complexity to the code and make bugs more likely to slip through - and there's a chance for them to break unnoticed, if they're not something the dev version is consistently tested with.
Never mind suggestions for making certain
game mechanics optional. I don't even want to get into that

In short - options need to pull their weight. In this particular case, having an option in the UI that only makes sense for a few specific mods would be confusing to anyone playing vanilla. The csv approach would make more sense, and I'll keep it in mind.
