For that we don't actually need to do anything, e.g., not need to
explicitly set a maxFeatures.

The reason the limit was set up is to make sure the browser does not
get overwhelmed, getting a few hundred thousands features in XML
will make Firefox use a inordinate amount of memory.

So whatever we do someone will get hurt, either by not realizing
the feature limit, or by having the browser explode in its face.
