Count me in as another one using recessed cleats.
I've got some carbon-soled Shimano shoes that I use on the MTB and my road bike. All three of my bikes have got Crank Bros Candys so I don't need to match the shoe to the bike. It's not 'purist' but it works a treat and in any case I'm not out to race - I feel very confident clipping in and out whether on or off road. And like others have said, you can walk in them! I also have a pair of 'casual trainer'-style Shimano shoes that I can wear to work, so I don't have to wear the stiff soled ones all day, or carry office shoes in a rucksack.
Point taken about replacing the cleats as per the OP though - mine have been heavily used over the years and are getting a little bit loose.
