$:/palette does not support text referencing

Merely curious as to why $:/palette does not support text referencing. This severely restricts the utility of $:/palette. Should it support text referencing or wikitext, I could employ conditional logic for selection and evaluation. Alternatively, I could delegate processing to another entry, requiring only the import of that entry’s values within $:/palette. However, after numerous attempts, I found this entirely unfeasible—even referencing its own field values proves impossible.

I’m curious as to why this is the case – is it a bug worth fixing, or was it deliberately designed this way?
