The option to ignore the cycles is there, added to allow for people to

You can also embed the option into the executable. See the bottom of
https://dlang.org/spec/garbage.html#gc_config.
I didn't know that! Very nice, and a good mechanism to help those with
deprecation issues -- if you put the oncycle=print in that list of
options, then the new code will still run when a cycle is present, and
old runtime will simply ignore that. No need to add the option when running.
Is there another place where --DRT-options are listed?
I don't think so. Probably a good idea to list somewhere. As there is no
central processing of options (they are parsed, but not handled until
requested), it's less obvious where all the usages are. I only found the
GC options and maybe one other.
