Use the official process.
Note: When this official process was introduced, moderators were initially strongly discouraged from escalating older bugs and feature request questionsposts which didn't fit the current quarter's priorities. However, that changed several months after introductionthat is no longer the case. Now, moderators can add status-review to any bug or feature-request question, regardless of age, at the moderator's discretion. However, questionsQuestions which don't fit the topics for the current quarter are likely to be assigned a lower priority, but SE staff will at least be aware of them.
