yes probably. 
Hristov and I were trying to understand what is the right approach following up the comment mentioned in the PR description (https://github.com/llvm/llvm-project/pull/73617/changes#r1416641551).
We are not sure if just this one line would suffice or if we should add something else. Do you have any ideas? Thanks
