Summary:                    On omitting the T flag from Dial() the caller can
still make a blind transfer
Description: 
I use allowtransfer=yes in sip.conf. I think if I omit the T flag from
Dial() in a dialplan extension, no blind transfer should be made by the
caller. But the caller can still make a blind transfer if he presses the
TRANSFER key.

A partial workaround is if I set allowtransfer=no in sip.conf, but this
will disable the blind transfer initiated by the caller side as well (which
is not what I would like to).

That would be correct. Could you please clarify, the phone that is
initiating the transfer, is it sending the key sequence specified in
features.conf on YOUR system when the PHONE's transfer button is pressed,
or is it performing a transfer via sip REFER?
