Right.

Using a fake baselayer might be a workaround.

Another way might be to override map.isValidLonLat and use
this.maxExtent instead of this.getMaxExtent() for the validation of
the lonlat.

And this makes me wonder if it would make sense to have isValidLonLat
use this.options.maxExtent if it's defined (and
this.baselayer.maxExtent if it's not).

Another area of interest for OL 3 I guess :-)
