In most practices these two halves belong to different people. A general dentist refers the extraction out to a surgeon; months later somebody else works out what goes back in the space. Between them sits a handover, and the handover is where the plan gets lost.
Here it is one practice and one plan. The extraction is performed knowing exactly what is going into the site afterwards, which changes how it is performed — how much bone is preserved, whether a graft goes in at the same visit, where the implant will need to sit eighteen weeks later.
That is the whole argument for comprehensive care, and it is not an abstract one. It is the difference between a socket that is ready for an implant and one that has to be rebuilt first.
