One good argument for having block delimiters is for embedded situations like 
ASP.  One can conditionally put code into a block as such (ASP is rusty):

<%
		if (some_condition) {
%>
	<tr>
		<td>some data</td>
		<td>some more data</td>
	</tr>
<%
	} // closing curly
%>

I would think that for embedding python, having block delimiters would be 
beneficial.
