It would appear that the path-of-least-resistance at present, is systemd, poettering which is what is (for systemd-booters) where fq_codel is getting turned-on in ubuntu.
This raises a wider-issue about bringing systemd-provided sysctl- defaults into procps more widely [systemd has introduced many of these in its' own repository, but version in ubuntu-bionic has few, see /usr/lib/sysctl.d/ on a bionic system... ALSO I have discovered there are facts to be checked about "BBR" as default TCP congestion-control, which will also be desirable, but MAY still have immature/issues when ECN is used on a TCP connection as well [one suggestion BBR doesn't react to ECN notifications]... I'm trying to get 'evidence' and 'facts' in that regard, which seem to be sparse and hard-to-find ... I'm going to (try) to get more facts before suggesting patches with reasons/evidence a few places. Agree entirely debian and upstream worth trying to ask, etc. HOWEVER its' often very useful to have had a change introduced in a 'non-lts' or 'testing' distibution like ubuntu-non-LTS releases so you can say how it works and had some testing/exposure somewhere first... It may be I come back to you and suggest a delta in ubuntu "for now" for good reason. We will see.
