Thanks for reporting and working on this.
I do not think this is worth doing - D10 CHANGELOG.txt was changed and it does not contain such information anymore, see: https://api.drupal.org/api/drupal/core%21CHANGELOG.txt/10 (and #2647824: [policy and patch] Determine what should go in CHANGELOG.txt for 8.x core releases → ). The file never contained information about all D7 releases. Agree with David comment #4, that adding all D6 releases would duplicate fair amount of fixes, as most of them were backported from D7 to D6 in later phases.
We will continue with adding short changelog entries on each D7 release until the D7 EOL. But regarding the D6 entries, I think the best approach is to close this as Won't fix.
