I have shot many SDF approaches. The difference is it's either 6 or 12
degrees and you don't know which. As long as the needle is in the center it
doesn't matter. Usually you are aligned with the runway, but it may not
align you with the runway, as are some ILS approaches. There is NOTHING
wrong with these approaches.

For all practical purposes, you can treat the LDA and SDF as a poorly
designed Localizer approach. LDA is not aligned with the runway, and
SDF may or may be aligned and has a larger course width. Here are some
examples: LDA/DME-18 @ TVL, LDA-C @ VNY, SDF10 @ DWU
