In my case it did.
And does this rc5 boot entry appear in GRUB but just isn't the default? Or is it missing?
For me I think it didn't appear at all, but I'm not 100% sure. Even if it appeared, would it work? Would grub know to look for the files on the ESP?
It should be easy to experiment with this, anyway - all you need to do is have systemd 250 installed, and create the directories /boot/efi/loader/entries and /boot/efi/(yourmachineid). Doing so will reproduce the bug, and you can run kernel-install yourself and have it create this style of entry and see what it looks like and how it works.
