In layout composer, in atlas, when adding a field for an expression as `attribute( @atlasfeature, 'myfield' )` myfield is added with double quotes instead of double quotes

That's because it's adding the "object_id" attribute for the atlas feature, not the string literal 'object_id'. I.e. get the value for the current fearure of object_id (say, "5"), and then get the attribute from that feature with matching field name (field with name "5").
It's the same behaviour everywhere with expressions.
