Hi.
I remember the Monolog topic, here: Feature #94600: Use Monolog for injected logging services - TYPO3 Core - TYPO3 Forge
Please interview the people that were involved in the (abondoned) change, here: https://review.typo3.org/c/Packages/TYPO3.CMS/+/70014 in order to get their experience in the logging topic.
Cheers
