I think that following this change, the "type" property of the existing macro definitions appears as deprecated, for example for the standard MentionsMacro:

Is this the intended behaviour? I wouldn't really expect it:

• I thought string was automatically convertible to static list single select, so I am not sure why this appears as deprecated?
• the need is just to add suggestions & keywords, so functionally it doesn't make sense to have to update all macro definitions. As mentioned above, the data type itself doesn't / shouldn't change...
