Because eventually someone would coin some kind of phrase for making soap with lye that doesn't fall in to those categories and then ask for it to be included.
When we all look the sub-forum names in general, it will always take some thought as to where do I put my post, but that is the nature of a forum. For example:
"I am thinking of using this mix of EOs for my CP soap tomorrow - is it a good blend?" would be in the EO section as the main point is the scent itself.
"How much EO to add to my HP soap?" would be in the lye-based soap section as it is not so much about the EO itself.
When it comes to the LS/lye based decision, of course it comes down to whether the question pertains particularly to liquid soap (which is a VERY different beast from bar soap in many respects) or not. Do things survive lye, safety issues and so on are the same, but then dilution issues and particular questions would go in to the dedicated LS section.
It's not always perfect, but it is what it is.
