It's pretty common in systems where the final output to be deployed is the same as the root of the source tree. More often than not, lazy developers tend to just git clone the repo and point their web server's document root to the cloned source folder. In default configurations, .git is happily served to anyone asking for it.

This seems to be automatically mitigated in systems which might have a "build" / "compilation" phase, because for the application to work in the first place, you only need the compiled output to be deployed. For instance, Apache Tomcat.

Or you do a git clone/docker build and that grabs it.

Hidden files only attract the attention of pessimists.
