There aren't many P107s around here but there are plenty of post top installations with other 360 degree designs, although they are sadly disappearing which is a shame as the even light distribution works well in residential estates where the lighting needs to be as much for pedestrian use as for cars.I feel the same way... Even more modern dedicated post top lanterns like the WRTL 2000 can give a good illumination without light intruding into bedrooms. Where I used to live was at the end of a road where you had to go through a council estate area to get to it - and the road always used road lanterns as aversed to post tops, and it got relit using full cut off lanterns. Terrible choice, as the road went up hill slightly, and at night as you went up the hill every house front was dark and all the gardens dark as no light spread behind the lanterns - and it just the area feel really intimidating. In addition, not too long after the change, porch lights and badly-installed halogen floodlights started appearing on the houses as people didn't like their cars being in darkness.
A bit of light spill is needed on residential streets, even more so on council estates, and completely cutting that out isn't a wise idea in my books.
