Better integration of extended domain entities added by Solutions with native entities

There are some very helpful solution packages in TP that add new entities.  However, these often integrate poorly with native entities.  For example, we added the Product and Component structure which provides product versions.   These add capabilities that are not available in releases.  Product Versions are very useful for software products, especially ones we aren't developing internally.  However, they also lack some of the capabilities that are available in Releases.  Currently, our instance has Products, Product Versions, Releases, Packages and Builds.  Releases and Builds are native, the others were added via Solutions.  They all relate to similar concepts but each has particular capabilities missing in others - Project/Process-specificity, Workflows, Assignments, relationships to other entities, Planned dates, ability to be seen as "Current" or "Past" - all of these differ among this set of entities. 

It would be so much more powerful if your Solutions team took the time to think through how these might work together.  Some of the Solutions seem to have been added to address some specific request, without thinking through (or documenting) how they would be incorporated into an existing data model.  This is further complicated by the limitations of all extensible domain entities (for example, a custom field of type TP entity can't use an Ext Domain, many of the automation conditions and actions don't work with these extensible domain entities, and they often cannot be used in lanes of views as might be wished for). 

In addition to improving the data model to better incorporate these, we would value better documentation on best practices in using these packages.  The Solution documentation is often very thin (and the quality varies from one solution to another).  It can be really difficult to get anyone to explain how they are intended to be used since the support people seem to not have information themselves about Solutions.

I know your team is up to improving this!
