So, I'm not against this patch per se, but, I'm wondering if it's not
better to display this data in systemd-cgtop.

After all, systemd-analyze is a one-time snapshot and suffers from
data loss when services are restarted, etc.

Having a method to show cpuacct totals in systemd-cgtop seems much
more useful. You could modify the code to show totals instead of
percentages, etc.

Have you thought about doing that?
