It's not just any disk, it's the disk that grub-install is writing to on upgrade (iiutc), i.e. 'hd0,msdos2'. It should then boot (directly) from my NVMe drive, with has a gpt partition table. Pointing my BIOS to boot from that NVMe drive caused this problem for me and changing that to the drive-to-be-removed, fixed it.

I just checked and saw that even old-old-stable has version 2.02X, so I might have actually ran into this issue before, but just not remember it or I did not have this issue to begin with. I see/agree with your point and hopefully you won't have to deal with lots of bug reports like this. Cheers, Diederik
