Creating a *useful* Power BI Data Dictionary for Viewers?

My perception is Data Dictionaries usually fail (not just for Power BI, in general with tech). Maybe because

• Too complex and/or out of date for end users
• Too much hassle for developers to update (plus end users aren't using it anyway...viscious cycle)

I see different ways of auto-ish creating a data dictionary in Power BI, but while they could dazzle, they don't seem useful.

• In model view, populating the Descriptions - nice, clear spot, lives direclty in the report.
• Descriptions are only visible to builders though, not end-viewers. So to expose them:
  • XMLA Endpoints (if you have Fabric).
  • Using the new-ish built in views. These two stand out:
    • info.view.measures() for measure definitions
    • info.view.columns() for column information

But even those descriptions don't seem that useful to an end user.

• Column descriptions could be useful: If the visual the viewer sees, uses the exact column name
• Measures descriptions and definitions coudl be useful: If the visual the viewer sees, uses the exact same measure name (which usually they don't - the model measure likely has a verbose name, while the visual employes a shorter, possibly context-specific name)

So maybe, one really needs a data dictionary that references the actual visuals the viewer sees. So how to do that:

• A text box within the report is simplest: Easy to enter, doesn't make a report on Live Connection switch to a composite direct query. Can't have slicers though.
• Home > Enter Data: That creates a proper table one could use slicers on. But more of a pain to update than a text box, and does mean a live connection report has to swtich to a composite direct query model
• A linked Excel file: Great in most ways, but a bummer that it lives outside the report
• Images pasted in from an Excel file that lives somwhere

I have no good conclusion, thus asking for input.

Anyone had luck, with a sustained, useful data dictionary for Power BI report viewers?
