Is it worth to create a program for automatic finding all app usage user?

I saw it in official Blockstack Roadmap ( :

  • Release of anonymous analytics API to report on app usage, growth, and retention.

Does this mean that developers will have tools to find all users that use their apps ?

I wanna do selenium app (or maybe something other) that will automatically comminucates with blockstack core (maybe local due to spam blocks) and find all users that use my app
Is it worth to do ?
