The Jetpack team said users have a hard time knowing what features are available

This is an argument against creating megaplugins with dozens of unrelated modules that cover everything from CDNs to CPTs and contact forms.

The solution is to have smaller plugins dedicated to performing one task.

It’s easy for an average user to understand what Contact Form 7, Google XML Sitemaps, or Wordfence Security do based on their names. What does a Jetpack plugin do?

As Carl Hancock pointed out, hosts auto-installing JP without users’ input compounds the discoverability issue.

Allowing megaplugins to modify the search page as a solution to their self-created discoverability issues gives them an advantage over single purpose plugins by allowing them to appear at the top. It incentivizes the wrong thing, it will be gamed.
