What I was looking for is the process that triggers "offline updates mode". If it involves the bootloader, I know whatever it may be simply doesn't exist. This is a multiboot installation, so no Fedora bootloader is involved in its boot process. If not bootloader related, I'll go ahead and file a bug, or even if it is, but you indicate you want one anyway.

What triggers it is the creation of /system-update symlink and a reboot. Then systemd picks that up and for that boot considers system-update.target the default target.
So apparently the kernel cmdline can be involved, and the only bug appears to be that the wiki page has no boot stanza admonition that the cmdline must not include anything to avoid booting to the temporary default target (in this case "3", which is a parameter I include on most of my kernel cmdlines).
Last line on vtty1 ATM is "[OK] Reached target System Update". There's no way apparent to ensure anything is actually happening at this point, no login prompts or anything else on other vttys.
