Few doubts about the Risk customized workflows and forms

For the last 2 years we have been working intensively with the Workflows and Forms module. Mainly we have designed and configure items for a Project context.

Recently, to fit a use case within our client, we have started to customize a Risk workflow, and all the necessary forms to run it, and we came across with a few limitations we were not at all expecting, if we compared to the features of this module in a Project context.

1. We cannot enable discussions in the forms. As discussions are available at Risk level, why can't we have them in the forms, similarly to what happen with Projects? In fact, we have confirmed that Project context is the only one that we can enable discussions for now, which we find odd since we have this feature available to Projects for more than a year.
