Based on my experience so far, I think the best way to approach these refactoring tickets is to do them as part of other bugfixes or features, e.g. issues in $refactor_ticket contribute to the source of bugs or major obstacle in code readability / maintainability when fixing $other_ticket.

serg I created some refactoring tasks related to the Spider storage engine. Could you please check these tasks and advise me if I should work on each of them and how I should prioritize them?
