I realize this probably sounds pedantic, but please bear with me.
A recent question prompted this matter once again1: a user wants to start modding their Minecraft but runs into a problem, but the question is closed as "technical support for modded Minecraft".
I had a micro-discussion with user dly about this in the comments (using the spoiler format for visual distinction):
As I see it, the biggest problem with modded Minecraft is that there are so many variables (and bugs and bad programming) coming into play that giving the right solution to a problem is virtually impossible.
My dry, technical point is that I think we should make the distinction between 'modded Minecraft' and 'about-to-be-modded Minecraft'. The state of the latter Minecraft, no matter how you look at it, is non-modded.
Alternatively, we could phrase the close reason as "technical support for modding and modded Minecraft" or something similar.
Meta questions that deal with the problems with 'support for modded Minecraft' and 'technical support' are:
If needed, I can make a list of applicable passages from these questions.
1: "Once again" because this happens every now and then. It seems the words 'mod' and 'modded' in combination with a Minecraft question are enough grounds to use our highly specific, exclusive close reason.
