Henrique, Debian's amd64-maintainer, said that AMD64 processor microcode and AMD SEV are packaged together as AMD's microcodes have caused regression in the past and are therefore easier to maintain without other firmwares. Indeed, the Ubuntu Security Team has needed to revert regressions caused by the microcode as well (LP: #1779092, LP: #1853614). Debian never packaged AMD SEV with other firmwares, so amd64-microcode was a logical package to add it to.
Additionally, users who need AMD SEV may need AMD64 microcode.
I will prepare this merge without deltas and prepare a patch to remove AMD SEV from linux-firmware.
Appreciate your guidance @superm1!
