Summary

Matomo currently supports the Do-Not-Track-Header that was introduced by some browser years ago. The option to exclude visitors sending this header is even enabled by default.

In 2019 W3C closed the group that was working on the DNT standard and though this is meanwhile deprecated.

Safari removed the support for DNT for privacy reasons shorty after that in version 12.1.

In matter of GDPR the DNT header does also not need to be respected.

We should there no longer enabled the DNT option by default in Matomo and add a useful information explaining why this feature now is deprecated and might be removed in an upcoming major release if more browsers drop the support.
