The console plugin only applies to Joomla 4 and is only used by Joomla 4's cli/joomla.php CLI client. It doesn't do anything on Joomla 3. Moreover, since it's written as a native Joomla 4 plugin — which uses a different naming convention for language files — it appears untranslated on Joomla 3.
If you had installed Akeeba Backup 7.5.0 in the past you need to uninstall this plugin (if you skipped 7.5.0 and went directly to 7.5.0.1 you don't need to do that). The console plugin will remain uninstalled in Joomla 3, even when you eventually upgrade to a newer version of Akeeba Backup. When you upgrade to Joomla 4 you can install either the same or a newer Akeeba Backup version and the plugin will magically install itself again.
The way this is implemented is a bit backwards since it tries to work around Joomla's extensions installer. We can't tell the installer which extensions in a package to install and which to skip. We can only run a short post-installation script. What we do is detect if we are on Joomla 3 and if the console plugin had not been already installed before the Akeeba Backup update ran. If this is the case, we uninstall the console plugin Joomla just installed for us. If it's Joomla 4 we let it be installed and we automatically activate it if it was just installed.
