we usually use /32 to not waste ip addresses. in BGP loopabcks are used for the peering between iBGP peers or sometimes netween eBGP peers having redundant connection but it's not mandatory to announce the loopback into BGp process.
the loopback is not only an interface or a logical host or a tool for troubleshooting. A loopback is a TYPE OF NETWORK as much as a point-to-point network, point-to-multipoint network and so on. This is mainly a cisco implementation of it and especially works in this way with OSPF.
It is a curios experiment you can do to set a loopback with a /24 address and to see on the other end of your OSPF domain how the same loopback is advertised. You will find that, if you do not further modify the loopback configuration, your /24 subnet will be advertised as a /32!!!
