tl;dr: the Debian default is the same as you have, even under systemd.
Partitioning is only relevant if you allocate a /tmp partition and
configure it in fstab, in which case systemd (and hopefully all other
inits) will respect that.
Debian's systemd defaults to leaving /tmp part of the root filesystem,
but with a one-time migration to tmpfs /tmp if previously configured
by enabling tmp.mount or setting RAMTMP=yes. This is a Debian-specific
change, and could be reverted if there's ever consensus that it should be.
Upstream systemd uses tmpfs /tmp by default. This can be prevented
by masking tmp.mount, or reconfigured by mentioning /tmp (as
tmpfs, a disk partition or even a bind mount) in fstab, as part of the
general rule that /etc takes precedence over /[usr/]lib.
