Being able to remove edges between surfaces means that the surfaces need to be combined into one larger single surface.

That becomes difficult when the surfaces are touching at internal trimmed edges rather than at a natural edge of their underlying surfaces.

Please see this FAQ entry for some more description on trimmed surfaces and underlying surfaces:

http://moi3d.com/wiki/FAQ#Q:_Why_does_show_points_work_for_some_objects_but_not_others.3F

In your particular case here it looks like you want to have the edge removed between these 2 surfaces:



But look at how the control points of the upper planar surface are positioned - (use edit>separate to break it into a single individual surface and then you can turn on its control points):




Then look at how the control points of the rounded side piece are positioned:




So you can see there that the top planar surface has just 4 control points for its surface and they are not located anywhere near the actual edge - that's because that's a trim edge. Trim edges mark regions of a surface that are holes or cut off areas.

So because those 2 underlying surfaces have no alignment between them in their surface control point grid, there isn't really any way for MoI to glue them together into a single surface - to make a single surface means to make one single rectangular control point grid out of them.

A rebuild that would do that would be trying to rebuild the surface only by looking at its trim edges and not by looking at the actual surface itself - that kind of rebuild would be sensitive to all kinds of variations in edge topology and would be quite difficult to implement...

Anyway, I just wanted to give you some explanation of why that request is quite difficult to achieve.

In your final example it looks like you've used a totally different method to create that, probably something like a revolve? It's very difficult for a computer algorithm to be able to sense stuff like that to try and recognize that a revolve of some larger edge would work to rebuild those surfaces - just in general things that rely on judgment are difficult to implement in a processing algorithm without stuff like artificial intelligence.
