hard edges connected = soft edge

[maker]

First off, I'm not sure if this is a bug (or just an irritation ). But here goes, anyway, with an example:

Convert all edges of Cube to Hard.
Connect any two edges. The new edge is Soft.
Convert it to Hard, and extrude the small face created.
Result - a face with soft edges.

Bit of a problem for (non-Gehry-type) Architectural modelling. Esp if I extrude a lot of faces simultaneously - and some edges of object are Soft.

Is there any setting to make default edges Hard?
