About future integrations of new works under FRAF's umbrella

So, I hope it's in the good topic, didn't know if it belonged to here or to "Forums meta"... anyway.

There's a topic in which people are talking about the fanworks they wish would join FRAF, but I'm personally wondering: how did the current works under their umbrella got here? And will there be new integrations in the future?

If one of those questions was already answered, apologies. But I'm still curious about that so if anyone from FRAF/the HICU who is able to respond sees this, I would be interested in learning more.
