In the past it was usually recommended to have a separate /boot

default now is to not create this partition, and to instead install
the bootcode into "/" directly, with /boot being a subfolder of the
root partition.

Has something changed with regards to "best practices," or is there
another reason that this is the default now?

ISTR that way back in time, boot loaders had trouble reading past the
first 1024 cylinders of the disk. That limitation was lifted long ago,
but having a separate /boot partition was a way of working around it.

What you wrote is _ONE_ reason for having /boot on a separate partition.
The 1024 cylinder limitation is indeed a old relic.

However, there is still a good reason for doing so:
If you need full disk encryption (as in: root + swap), you still
need /boot in an unencrypted area, because grub needs access to the
kernel and initrd

grub2 used in 13.2 may be able to read it (it supports LUKS
