​I would take the first feature's attributes because I've seen multiple
times that input datasets for aggregation algorithms (such as hulls,
dissolve, ...) are prepared in a way that the result represents a certain
class, e.g. all points where column "type" value is 'tree'. Why should we
delete the 'tree' value then ... ​
