How to substitute datamart?

Hi, this is a follow up question gently answered by Greg_Deckler 

I created a datamart and I would like to change this solution because it is unlikely to ever get GA. The solution work perfect but I see a risk that datamart might be deprecated at any moment, as was recently machine learning in dataflow. 

My client is a medium sized organisation. Using a PPU licence, I created some dataflows with large volume of data that includes computed tables. Using the SQL endpoint of the datamart, I shared these computed table to other developers with Pro licences and therefore avoid paying many PPU licences. This solution is cheap and efficient.

I'm looking for alternatives

• I can give PPU licence to every user of the organisation (which is more expensive)
• I can pay for a Fabric capacity (which is more expensive)

Have you got any other ideas that won't be more expensive?

thanks you all
