Ohh, I had a case of code blindness; I misread it as
```cpp
if (Finder->getASTContext().getLangOpts().CPlusPlus20)
if (isa<CXXStdInitializerListExpr>(E))
return false;
```
Thank you for the explanation, now it makes sense ^_^

As for "don't warn" vs "warn with a different message" on temporaries: if we do
need to have a design discussion, I think it makes sense to have it now (here
or under that issue). But also let's wait for @5chmidti's opinion
