So far in 2019, the gap has narrowed: "only" 45 CVEs so far for the Linux kernel, and 7 for systemd.
This contributes to the low rate of CVEs in systemd relative to Linux (for which many less-important bugs get CVEs).
My conclusion is that the systemd project is not its own CNA and therefore not in a position to authoritatively decide which systemd bugs get CVE numbers assigned and which do not.

For a piece of software used by millions of machines, that's a very low CVE count.
