How to log plugin errors to plugin error_log file

How can errors, specific to a given plugin, be logged to an error_log file contained within the plugin root folder itself?

Examples:

• Syntax errors
• Database errors
• Compatibility errors
• PHP fatal errors
• Ajax request errors

Similar to the /wp-content/debug.log file enable when WP_DEBUG_LOG is defined as true in the wp-config.php file (albeit specifically for plugins with its concerns separated from any other general error unrelated to the plugin itself).

Research:

Debugging Plugins section in the official documentation of the Codex refers to using 3^rd party plugins to debug 3^rd party plugins.

Don’t Develop Without Debugging^{by Smashing Magazine} refers to site-wide general debugging.

Plugin Handbook appears to layout no specific guidelines.

By setting the second argument to 3 for error_log:

$pluginlog = plugin_dir_path(__FILE__).'debug.log';
$message="SOME ERROR".PHP_EOL;
error_log($message, 3, $pluginlog);
