tab at beginning of line does not indent any more

[Mandar Mitra]

I have org 20210929 installed. 

With emacs -Q and (package-initialize) evaluted in the *scratch* buffer, I see 
the following change in behaviour:

* ABCD
<type tab here at beginning of line; nothing happens>



I'm fairly sure that, before the last upgrade, I used to get 

* ABCD
  <typing tab at beginning of line indents the line and brings it to under A>


Have other users observed this? Are you bothered by it? Is this a bug or a 
feature? Note I'm running with emacs -Q for the above, but I get the same 
behaviour with org-cycle-emulate-tab set to t or white. The information I found 
on the net seems to pertain to much older versions. 

Thanks,
Mandar.
