This old binaries were prepared by me, Jason and Haris prepared new
binaries. My binaries are built using VC++ 2005 + SP1 and the SP1 makes
problems for Jason and others. Unfortunately, I can not remove SP1 from
my installation.

A 1-2 weeks ago, I was trying to download latest Map 3D but without any
success. I'm getting message that there is no binary prepared for my
location (geographical) :-)

I have to confess that because of Jason needs the provider tested with
MapGuide, and due to my current time limitations, I dropped testing with
Map 3D for a while and focused on MapGuide only.

Second, yes, there is some issue with geometries check-in, only OGC (2D)
geometries can be inserted/updated for now.

Yes, this is ongoing development, however I've been very busy with
my other activities recently.
Current version is the very first release of the provider. This is not a
small piece of software, so it needs time for polishing, fixing, etc.

Generally, I will continue work on the provider as my time permits,
as I'm a volunteer contributor, but I can assure that at first place,
I'll do my best to fix bugs in currently available operations.

Yes, it is.
So far, I've tested only simple cases like:

My personal opinion is, not it's not too early.

The provider is out and usable, but there are hundreds of operations
implemented and clearly it's not surprising there are still some issues,
trivial as well as crucial.
