No recall.
Why? $$$



It boils down to personal preference as they all work equally well.

Getting to the IPDM-E/R, where the fuse lives, requires removal of some panels in the engine compartment and removal of the IPDM. An easy job if you have any experience working with cars, but might scare off those without experience. If you want to re-enable the SLU, just put the fuse back in. This is the option I chose.

Cutting the wire is very easy (just requires something to cut the wire), but will be the most difficult to return to factory condition if needed (eg, for resale, gov't inspection, &c). I would consider this a permanent fix with no going back.

The harness extension does exactly what cutting the wire does but it's not permanent. An easy install, but costs $50 + shipping. It has connectors on the "broken" power wire so you can add a switch and enable/disable as you please.
