Yes, you may have noticed that we have been working through our backlog of suggestions quite vigorously recently (over the course of RC, we closed over 30). We've reached back to 2010 for a number, so we are getting to them. If we don't plan on getting to one, we generally say so and close the request.
It is unlikely this particular one will appear in 4.1 due to time reasons. RC 3 is supposed to feature-lock the branch, which as the XF2 support branch, wasn't really going to be a full feature branch. We included a small number because:
- They are a baseline for some stuff scheduled for 4.2 (mostly the old 4.1 designation that had to be renumbered and pushed due to XF2's release).
- We will need them to fully migrate off of vBulletin over the next few months.
- To resolve a regression.
- They added to a feeling of better integration with XenForo 2.
There was a debate on whether to include this in RC 3, and it got thrown around quite a bit over the past few months, so it is not ignored.
This is pretty well spelled out in terms of the design, so it's just a question of scheduling - what features build on top of each other, need related new code, or are similar to each other thematically. 4.2 is going to be a full feature release, and will have a lot of things people have been waiting for. I don't see this being pushed later than that. We will be dropping support for some old forum versions to improve development speed.
It should also go faster due to the fact that we basically just rewrote the entire framework in 4.1 to make it run better (more tightly) on XenForo. Not including testing, that took about 9 months, which was time not spent on any features at all. It's work that doesn't need to be done now, so apart from our site migration, it will be full steam ahead with features and 4.2.
