We researched Data Protection and Security Issues With Network Error Logging and it seems that we should add a shield to JShelter to protect users from NEL tracking.
Pages affected: The deployment raised from 0 to 11.73 % (almost 2,250,000 unique domains) since 2019. Current deployment is dominated by Cloudflare. See https://arxiv.org/pdf/2305.01249.pdf.
We will work on the issue after migration to MV3.
