There is an industry standard keymap being made, specifically for this.
I can give you incontrovertible reasons for why double click to select edge loops is redundant, and worse than the current method of selecting edge loops.
It’s not about confusing a double or single click, and blender is not an operating system file explorer where things happen slowly and ui elements and controls rarely overlap. It’s about redundancy, a pointless extra keybind, conflicting with a feature and breaking a design philosophy present in a large portion of blender’s workflow and keymap design.
The conflict is that it will break flow, and require the user to be aware any time they select things to not press the mouse button too quickly.
Being aware of this slows down normal clicks by more than just the factor used as the speed of double clicks, because the user is immensely likely to over-compensate so they can be absolutely sure the computer won’t register a double lick.
This is thinking that takes you away from what you’re working on, and instead forces you to think about how the computer is going to interpret what you’re doing, which is contrary to the design of the general blender keymap and controls used thus far. This design philosophy is in large part responsible for the flow state and speed a user can acquire whilst using blender.
