I think you want to use one of the default templates (or create your own) :
{{||$:/core/templates/tiddler-metadata}}
If you still want to use a filter expression you can use this :
{{{[is[current]fields[]!match[text]]:reduce[<..currentTiddler>get<currentTiddler>addprefix[:
]addprefix<currentTiddler>format:titlelist[]addprefix[
]addprefix<accumulator>]+[enlist-input[]]}}}
or using your more elegant method :
{{{
[is[current]fields[]!match[text]]:map[<..currentTiddler>get<currentTiddler>addprefix[:
]addprefix<currentTiddler>] }}}
