I mostly participate in the Hermeneutics Stack Exchange, but will occasionally check out a few questions on this site. For obvious reasons, these two sister sites are very closely-knit due to the adjacency of the topics, with many contributors participating on both sites.
I have frequently noticed questions on this site that would be a perfect fit for the Hermeneutics SE, and some of them are migrated, but I also see a lot of questions that would be a perfect fit pass by without migration. The Hermeneutics SE is actually one of the 5 oldest sites that have not been promoted from beta according to Area 51 and has been around for a very long time and I notice that amongst the oldest sites, the most common metric lacking a green status is the "number of questions per day" metric.
I know that the Christianity SE began about two years earlier than Hermeneutics, and even after that it may not have been clear if the site would pass beta, so it is understandable that Christianity.SE might take general Biblical interpretation questions historically, but now that there is a dedicated SE for these types of questions, should Christianity.SE continue to accept these types of questions?
If not, should they be migrated? I know that often, questions are closed with a post notice stating,
This question exists because it has historical significance, but it is not considered a good, on-topic question for this site, so please do not use it as evidence that you can ask similar questions here. This question and its answers are frozen and cannot be changed. More info: help center.
Should questions of this type be closed with this status? It seems to me that by migrating questions of these types, it would allow the Hermeneutics SE to better flourish (and perhaps escape beta purgatory) and allow Christianity.SE to better focus on providing quality content of the type at which it excels. In short, should these types of questions continue to be considered on-topic?
