Hi! If you're looking for a developer friendly indoor mapping suite (both for editing and viewing/navigating), check us out - www.mappedin.com
Totally agree that it's an overlooked problem and we've been quietly working to solve it for years. Early on we realized the key was to build "everyman" mapping tools that facility managers can use themselves to keep data up to date.
We're increasingly focused on our developer-facing tools and I'd love any feedback if you end up taking a look! (https://www.mappedin.com/mapping/sdks/)
