I think the switch to arc with cycle detection as opt out (like
in python) is the right direction, it fits more to a system level
language making use of destructors more often.
Rewriting cyclic code to acyclic code is easier than lifetime
management in general.
Further, optimizations can be introduced that detect acyclic
structures in D just as it is the case for nim
(https://nim-lang.org/docs/manual.html#pragmas-acyclic-pragma).
That doesn't mean tracing GC is bad, I'm still skeptical that arc
+ cycle detection is better than tracing in general for true high
level languages.
