This looks promising, but, does it mean that it's not available in the Beta or should I be able to test now:

1.2.2.7 Changes to COM behavior for Object-Assisted Reporting
Object-Assisted Reporting makes REPORT FORM-based output an appealing
scenario for B2B data translations, HTML output on the web, etc.
To facilitate this extended use of REPORT FORMs, we will change the behavior
of the REPORT FORM command in COM servers as follows:

REPORT FORM will not be disallowed as a user-interface command automatically
if the REPORT FORM is executing in Object-Assisted mode (a Listener is used
to Render).

We will recommend that SYS(2335,0) still be used to trap for any modal
states such as an Open dialog occurring if a data table in the report’s data
environment is not found.

If the ReportListener executing in a COM server finds that it is set to
ListenerType 1 (Preview), it will automatically switch to ListenerType 3
(all pages rendered at once, no REPORTPREVIEW.APP invocation).

Quietmode will default to .T. for all COM states.

The new-in-VFP9 SET TABLEPROMPT OFF feature may be useful to people using
REPORT FORM commands in COM objects as well.
