Drop 'rare sampling' support on CSS #9776

amarziali · 2025-10-16T13:13:07Z

What Does This Do

It avoid force keeping the first seen spans even if they are p0. The rationale behind is that rare sampling is going to be discontinued. This feature is also not part of CSS hence we're removing from the old implementation.

The fact that rare sampling is not compatible hence with CSS is a known limitation.
