Why do the other files get recompiled? they should be recompiled only if there is change in them.

I have no idea. That's what I'm seeing when working with my project.

Literally add one character to one of my liveview modules:

    Rebuilding...
    Compiling 67 files (.ex)

It's worth your time to investigate this, it's fixable. Check out mix xref to investigate dependency chains between files in your mix project.

In the project I work on, it turned out a module `use`d by almost every controller included a function (totally unused, btw) which, through a little bit of indirection, caused a circular compile-time dependency between all of them. So any change to any controller caused hundreds of files to rebuild.

Never heard of xref. I'll take a look thanks!
