Impossible to disconnect area that shares node with ordinary way

[GertG]

I am not sure if it is really impossible.
Since 0.5, i have tried and not succeed to separate
nodes that are used in common between a closed area
such as landuse=residential, and a highway=unclassified
My approach was split the (closed) ways forming the area, and rejoin using new created
way and combine; leave the original node to the way.
Splitting has become impossible. JOSM complains about mulitple ways
but selecting the area's way doesn't help.
I can only fix the problem by splitting the ordinary road; deleting the
parts connecting to the original node; draw a new way between the stubs, and combine.

Could a solution be provided to make that more elegant ?
I was thinking of a short command to:

• create 2 nodes close together ; one int clead area way, the other in the road way.
• a command to join two nodes (very handy tool in general)

Why not just delete the node common to both ways?

Unglue plugin helps to sperate the nodes.
