Hello. If I use the placeholder {{slug}} for the default value of a field, it doesn't work if the title field is not defined beforehand in the type. Is there a way to make it work without adding the title field?

On the other hand, can the "title" field be renamed to something else? I find it too opinionated, forcing you to use that field in your collections.

I've tested it and there's an issue: it only works if the "title" field exists in the frontmatter. If I set "frontMatter.taxonomy.seoTitleField" to another field, it uses it correctly. However, if the frontmatter doesn't contain a "title" field, it can't read it and doesn't display anything in the SEO section.
