I agree to what you write, just adding that there even
is a need for vertical positioning, to know which
floor...

Obviously important for some use, getting the
advertisement from the wrong floor

3gpp.org

22.071 or 072??

4.2.2 Vertical Accuracy
For Value Added Services, and PLMN Operator Services, the following is applicable:
The LCS Server may provide the vertical location of an MS in terms of either absolute height/depth or relative height/depth to local ground level. The LCS Server shall allow a LCS Client to specify or negotiate the required vertical accuracy. The LCS Server shall normally attempt to satisfy or approach as closely as possible the requested or negotiated accuracy when other quality of service parameters are not in conflict.
The vertical accuracy may range from a about ten metres (e.g. to resolve within 1 floor of a building) to hundreds of metres.
For Emergency Services (where required by local regulatory requirements) there is no requirement for the support of vertical positioning.
