Yes. This is indeed what needs to be done with core.create_location.
<div><br>
</div>
<div>I'm not even sure if it was working correctly before anyway. I don't see how it could. Any problem with me updating it like this?</div>

In the GRASS python library, core.create_location needs to be updated to use the new datum argument in g.proj.
<div><br>
</div>
<div>I think I know how to update it, but it looks like there may be an error in the create_location code. It is using "datum" to refer to the "datumtrans" argument of g.proj. </div>
<div><br>
</div>
<div>Currently, the code looks like this</div>
<div><br>
</div>
<div>
<div>def create_location(dbase, location,</div>
<div> epsg = None, proj4 = None, filename = None, wkt = None,</div>
<div> datum = None, desc = None):</div>
<div><br>
</div>
<div>...</div>
<div> </div>
<div> kwargs = dict()</div>
<div> if datum:</div>
<div> kwargs['datum'] = datum</div>
</div>
<div><br>
</div>
<div>I think it probably should be:</div>
<div><br>
</div>
<div>
<div>def create_location(dbase, location,</div>
<div> epsg = None, proj4 = None, filename = None, wkt = None,</div>
<div> datum = None, datumtrans=None, desc = None):</div>
<div><br>
</div>
<div>...</div>
<div> </div>
<div> kwargs = dict()</div>
<div> if datum:</div>
<div> kwargs['datum'] = datum</div>
</div>
<div>
<div> if datumtrans:</div>
<div> kwargs['datumtrans'] = datumtrans</div>
</div>
<div><br>
</div>
<div>The programmers manual would need to be updated to reflect this change. This means a change in the arguments for create_location. But it is currently sending the wrong argument to g.proj anyway. So this is also a bug fix to create_location.</div>
