systemd has been recommending against an arrangement like that for a long time now. These partitions are often fragile (read from bootloader code, or worse firmware! VFAT has no data integrity), and they really have no reason to be mounted unless they're about to be accessed. Stacking the mount points like that requires /boot to be mounted to mount /efi, which is just unnecessary
So systemd & the Boot Loader Standard ( https://uapi-group.org/specifications/specs/boot_loader_specification/#mount-points) document separate /efi and /boot mount points, and recommend against /boot/efi. In all of systemd's code, /boot/efi is treated as a fallback of last resort, as a special case in the partition lookup logic, kept around for backwards compatibility with distros that haven't changed their layout to the recommended way. It's not even all that well supported/tested - it's been broken in gpt-auto-generator and warranted a breaking change to fix it. And systemd, left to its own devices, will never create such a mount layout (i.e. w/ gpt-auto-generator and root=tmpfs) So yes, in systemd /boot/efi is treated and thought of as obsolete. Distros not following systemd's recommendations doesn't make the layout any less deprecated from systemd's perspective. Perhaps Fedora can be adjusted to follow the BLS's recommended mount points?
