I expressed a judgement that, based on experience, there are potential

with complicated dependencies, that would be avoided by doing a clean

systemd and sysvinit in Jessie.
There is always a potential for problems.
However, if there are no actual problems, then there's no effective
difference between having systemd-sysv installed at some point in the
installation and then replacing it with sysvinit-core. If you find
actual problems, please file the bugs.
If you're really that concerned about this issue, it's also not that
difficult to roll your own version of d-i which contains the fix for
#668001, and use the --include/exclude options to debootstrap to fix it.
