They cannot, as I understood it, get the loyalty boost they want from converting a position to an F (Policy/Career) position because of the laws Biden introduced to protect roles from that kind of interference.

In April 2024, the Biden administration put into effect a regulation named "Upholding Civil Service Protections and Merit System Principles" (89 FR 24982) that allows employees to keep existing job protections even if their positions were reclassified, preventing most of the effects of a reinstatement of Schedule F.
So, again, getting these employees to leave of their own accord allows them to convert as many to Schedule Policy/Career as possible without the employee in the seat. Because Biden and Congress introduced protections that would have stopped them being dismissed.
And did you not read what Miller is quoted as saying? I don't know why you are arguing against the idea that the intent here is about loyalty to Trumpism, when they are saying that with their creepy little outside voices.
