When adding WFS (OGC-format) in a webmap it tries to render all objects in the layer and if it is more than the maximum it will not show all records. Official layers often contains many thousands of records and this makes it cumbersome to use WFS in a webmap at all.
An idea would be to enable a checkbox (WFC-OGC alternatives) that states "Only show records in visible extent" and create a bounding box (bbox) with the actual visible extent of the webmap
