Background

Joomla 5 and 6 both have an option to enable a Backwards Compatibility Plugin which is helpful especially in the early days of Joomla 5 and Joomla 6 whether upgrading or building a new website.

Issue

Once the website is built and running normally, it is easy to forget that the Backwards Compatibility Plugin is still enabled which can cause a number of issues including slower performance and potentially a greater effort required when upgrading to the next version of Joomla.

Proposed Solution

Joomla 1.5 included a "System - Legacy" plugin similar to the Joomla 5 and Joomla 6 Backwards Compatibility Plugins and included a "Legacy 1.0" indicator in the Joomla toolbar when the plugin was enabled (see below).

Can a "B/C Plugin Enabled" indicator be included in the Joomla 5 and Joomla 6 toolbar to remind Joomla website administrators that their website is not running optimally?
