Why is it advisable to avoid relying on short_open_tags for PHP code in the long term?

Using short_open_tags for PHP code is not advisable in the long term because it can lead to conflicts with XML declarations, can make the code less portable, and may not be supported in all PHP configurations. It is recommended to use the full `<?php` opening tag to ensure compatibility and consistency in your codebase.
