The LSA is a nice feature but, as you discovered, you do have to be diligent about following the registration process and it takes a long time. Getting service seems to be sort of subjective. Dad has been able to get his local Home Depot to take care of replacement batteries for him. I have had to go to a service center. Now that it has been a few years and I am on about the third set of free batteries, I get to just send the dead ones to the service center and they send me back new ones (cheaper than gas and my time). My sander developed a shimmy and I did have to take it to the service center (onl 40 miles one way for me) but, this is true of DeWalt, Delta and other brands.
Any sufficiently advanced technology is indistinguishable from magic.
