Feedback for Interactive Generator for Internal Analytics

Problem

The new generator for events and metrics implemented in !137323 (comment 1677810984) is a huge step forward, however since it's a radical departure from the existing generator it also opens up new potential problems, further iterations and ideas, which we shouldn't implement directly but rather stay iterative.

Desired Outcome

This issue is intended to collect feedback for the interactive generator implemented in !137323 (comment 1677810984) so that the feedback can be discussed and if necessary concrete issues for improvements can be created.
