I personally think we shouldn't as there doesn't seem to be much interest in actually running it. A lot of the IL categories are already empty, I don't think it would be wise to add a bunch more empty categories.
Honestly, I don't think we have enough IL runners to warrant the creation of a sub category for boost mode ILs, given that most of the IL boards are empty. I think we should just ban boost mode from ILs entirely.
If the IL category is already so sparse, if allowing Boost Mode is what gets anyone to add to it, I would say go ahead and allow it.
I have been running a few NSLU ILs and there are already a lot of different categories for Nabbit, Luigi, normal or secret exit and so on, I don't think we need more categories since some ILs are literally empty even if they are possible.
