The goal of this issue is to find a way to automatically notify Product team when any plugin has outdated code.
To safely assume that plugins don't get broken by Core platform changes, we need to automatically detect/ be notified of calls to deprecated functions or non-public APIs.
Note: the PHPStorm plugin can be installed on developers' PHPStorm so they can see issues as they code. (would have to enable the inspection & would be a problem w/ plugins that don't support the newest Piwik)
FYI: sensiolabs created a static code analysis tool to find usages of deprecated methods https://github.com/sensiolabs-de/deprecation-detector - this could maybe be interesting to us in the future
