In AutoCAD, most people are now using three variables with Annotation scale to control text , annotative blocks and linetypes.
Setting all 3 of these to 1 allows annotation scale to control linetypes with text and blocks. We can set our annotation scale in modelspace to match a plotting scale and see WYSIWYG for these things and then when we go to a layout, we can plot at 1:1 with a scaled viewport and assign an annotation scale to the viewport.
In DWG workmode, I was forced to set the LTSCALE in the layout to 12/<annotation scale> to get the linstyles to look correct. And I could not do this if I was in Read Only mode - which in some cases, I am forced to do to utilize object enablers.
For true DWG interoperability, MicroStation needs to be able to emulate this methodology.
I realize that Annotation scale is very different between the two platforms - but it is such a key component of both, that the ability to use either methodology is absolutely essential to claim true interoperability.
If implemented, the annotative nature of ARX Objects must also be supported and function as they do in AutoCAD and its verticals.
In non-DWG files, much of our work is client driven and they have not fully embraced Annotation Scale. So I am usually toggling off that reference setting, if that is what you are talking about.
As for DWG workmode, I am not sure I fully understand what you are asking.

LSTSCALE and PSLTSCALE are currently supported in MicroStation. MSLTSCALE shall be supported in a future major release, but it only impacts linestyle scale in Default model (aka modelspace). For viewports to work, a reference attachment needs to have its own annotation scale, as opposed to getting annotation scale from the source model or active model as it currently does. Beside the obvious need for DWG, do you (or other folks reading this thread) see practical benefits of making reference files to have annotation scales over using model's annotation scale as a general feature?
