In the latest post to Peter Petermann's site he shares a few thoughts about Composer and how people use it in the more modern PHP ecosystem.

Composer has changed the PHP ecosystem like now other tool introduced – almost everyone is using it today. Now, I have written about Composer before, and have always been a big proponent of using it. However, as i have spend some time with looking more closely on a few things, there is a few problems (some with Composer, some with how people (ab)use Composer) that I would like to write about.

He's broken the list up into six different point, each with a bit of explanation:

• Composer gets slow and resource hungry
• People are using composer as an installer
• People use their own paths
• People don’t adhere semver
• People don’t tag their releases / don’t release
• People release packages with dependencies to unstable versions

He ends the post by looking at each of these points and offering a brief one-liner way to help solve the issue (or at least minimize the problem).
