Today, Jason from Microsoft posted in the Answers forum about firmware updates to Insiders, saying that Microsoft is working on a way to make them available.
As it stands, Insiders don’t have access to firmware updates, as firmware updates are on the production servers, not on the Insider servers. In order to receive a firmware update, the Insider must roll back through the Windows Device Recovery Tool to get the update, and then update again through the Windows Insider Program.
Note that this is not about pushing out firmware updates without prior carrier approval. Your AT&T Microsoft Lumia 950 is not going to magically get the awesome firmware that everyone else has by now.
@rwoods716 Not all variants have been compiled/released, this is true. For users who don’t want to reset to get the new FW, this does that

This is about providing firmware updates that the user would be eligible for had they not been part of the Insider Program. In other words, they’re not providing anything new. They’re just fixing something that’s broken.
This whole carrier approval thing looks a lot better than it is. Microsoft can now push out software updates without carrier approval with Windows 10 Mobile; however, that’s exactly what you get through the Windows Insider Program. Firmware stll requires carrier approval and we still don’t have an answer for that.
While the firmware updates won’t make their way to the Insider servers for a few weeks, Microsoft recommends a workaround, which is to use the Windows Insider app to configure device for production (or to stop receiving Insider builds), get the firmware, and turn Insider Previews back on.
I have reached out to Microsoft for comment, asking if they do have any plans to bring non-carrier approved firmware updates to Insiders. I have no doubt that they’ll say “we have nothing more to share at this time”. For now, this is a step in the right direction.
