Massively impressive! A very exciting paper https://arxiv.org/abs/2009.12334v4 from the first two authors shows how Starlink can be fused with ordinary GNSS to get extremely impressive +56 dB anti-jam advantage (see Figure 1).

There is a paper out there where someone demonstrates that it would take 1.6% of constellation downlink capacity for StarLink to serve as its own GNSS. As you mention, the GPS network is very high quality, and would only make sense in areas where GPS was undeserving or active denial was expected (and StarLink had the capability to avoid jamming). Edit: I misrecalled. StarLink can provide 10x more precise positioning than GPS. https://www.telecomstechnews.com/news/2020/sep/28/starlink-s... https://arxiv.org/abs/2009.12334

To answer your question, yes. https://arxiv.org/abs/2009.12334 “This paper shows that continuous assured PNT (positioning, navigation, timing) service over ±60° latitude (covering 99.8% of the world's population) with positioning performance exceeding traditional GNSS pseudoranging would cost less than 0.8% of downlink capacity for the largest of the new constellations, SpaceX's Starlink.“
