I briefly skimmed through it. Overall, not impressed.
Some notables problems, which should be very familiar to readers of American think tank reports:
1. over reliance on extremely outdated information or sources
2. uncritical reading of translated PLA documents (e.g. concluding the PLA lack capability X because Y document says "we must strengthen X")
3. completely absurd scenarios that ignores preparatory phases before the invasion
4. Recycled articles from the 2010s with just passing mentions of new PLA capability, completely ignoring how these capabilities fundamentally invalidates previously made core assumptions
This is a boilerplate US think tank report that could have been written in 2017. What is funny is that its recommendations for Taiwan is functionally identical to reports a decade ago, but over that time the RoCArF didn't change much but the PLA is completely unrecognizable.
I didn't skim it, but I Ctrl+F the word 'drone'.
It only appears 15 times. 2 times is in the references, a few times were in reference to opportunities for Taiwan, and another to mention a US lead in long range drones.
I don't think drones are the end all of the discussion, but I think it certainly illustrates point 4
