@mjg59 on my windows laptop here bitlocker locks to 0, 2, 4, 8, 9, 10, 11. Which I think is today's default on modern Windows. (I certainly didn't change it). PCR 7 is not included interestingly.
And I think the TPM stuff in windows pretty much works, no?
systemd-pcrlock tries to lock to even more PCRs by default (but might exclude some if there are measurements we don't recognize).
