The chipset and socket have nothing to do with each other. Also, the engineering involved in changing a socket is trivial, relative to many other things.
The only reason for AMD to keep the AM3+ socket is to hold on to what market share they have by providing easier upgrade options. They could easily produce a new LGA socket with superior electrical characteristics, or adapt one of the ones they already have.

Because CPUs are planned
out years in advance and features of one generation are not finalized before those of the preceding generation, even if the release
of the former follows the design of the later.
Anyway, LGA-1155 is not LGA-1156 with a missing pin; there was significant reorganization. This isn't to say that Intel could not have made sandy and ivy compatible with LGA-1156, but the differences aren't as trivial as you imply.

They are pretty close, as far as consumer sockets are concerned.
Since I've been building my own systems (the mid 90s), there have been a dozen Intel consumer sockets released, and either 12 or 14 AMD consumer sockets (AMD CPUs used to be drop in replacements for Intel parts and used the same socket).
