    Description

      Why?

      Cause

      • Example use case: if tire-pressure change in all four wheels at the moment now each one need to be split to separated emits. After the change you would get this all once.

      Customer

      • ?
      • Technically: more common use case than singleton also harder to work-around than singleton

      Cruft

      • No customer had wanted this since Qt 6.7, why would need it now?
