Restrict Power Bi Access to Sharepoint List

Hi, anyone knows if Microsoft will address this? It's a big backdoor. MS is encouraging to use powerapps, with lists and sharepoint to store information as it's easy, but they should have implemented mechanisms to not expose data juat doing a simple connection to a site.
Yes, I know, you can restrict direct access by modifying the list permissions but as you have read permissions, because powerapp needs it, powerbi allow access. 

MS should give a answer to this establishing policies to restrict some connectors, even datasources, in a corporate environments
