Sure, you are aware that many of my buildroot patches are stuck in limbo
since early 2020?
Just doesnt seem feasible to timely fix everything and version bumps often leave
more untapped options. Some part of the necessity would be just being pragmatic.

One example would be using the unified cgroups hierarchy
(-Ddefault-hierarchy=unified), hybrid is pretty much deprecated,
and some systemd features that buildroot allows to enable (OOMD for example)
wont work without it.

FYI those are the ones I currently use:

-Ddefault-hierarchy=unified \
-Dutmp=false \
-Ddefault-dnssec=no \
-Didn=false \
-Denvironment-d=false \
-Dxdg-autostart=false \
-Ddns-over-tls=false \
-Ddefault-llmnr=no \
-Ddns-over-tls=false \
-Ddefault-mdns=no \
-Dlz4=false
