As I read it, it's definitely the 1-arg form (always), not the default ctor.
auto a = NoDestructor(); // NoDestructor a;
auto b = NoDestructor{}; // NoDestructor b{};
auto c = NoDestructor({}); // NoDestructor c({});
auto d = NoDestructor{{}}; // NoDestructor d{{}};
The actual chromium code is something like
template class NoDestructor { ... }
and is used as
NoDestructor> google_tlds({"foo"});
which means ({}), if it appears, was intended to mean the empty set, and this
empty set is passed as the first and only parameter to the NoDestructor 1-arg
ctor.

Don't write weird code?
Either of these works fine and is obvious what it is supposed to do:
NoDestructor b;
NoDestructor b{};
The original is weird. Is it trying to construct an 'a' object and pass that to
the NoDestructor? Or just default construct the NoDestructor object?
