reusing data source



I am looking for feedback on other experiences.


Today we build data models and reports in the same .pbix and deploy them.  We are starting to use shared data source for multiple .pbix reports.  I am comfortable with this.


In doing this, i was curious if it is a best practice to always have a backend data source and front end report file.  Meaning, create 1 .pbix that is just the full prepped data model with all power quuery and dax completed, publish that, and then connect a 2nd file as the front end report file (even if you only plan to use the data source once).


Has anyone done this?  What is your experience (e.g. are the refresh times impacted good/bad when developing, does it impact the user's speed experience, etc).
