I don't know how it works today as I'm not playing currently.
So I rather describe what I would like to see, not the changes to the current system (it may already work as I like and that's good)

I can live without 3rd option as well, but I see (dumb) people vote for it.
If they want, give them.
I just don't want to lose first two options as I prefer the effect of the wield command to be strictly deterministic. For example, I don't want my offhand to be removed if I try to wield my primary weapon.
