It wasn't properly documented, it is obscure as all heck, and early microcode updates active by default is a very recent development on distros.
You cannot even find "dis_ucode_ldr" being cited by anyone through google searches.
I believe it is actually possible to fix this still: either by directly renaming, or by using a deprecation period and testing for a new name and the "dis_ucode_ldr" name.
