Oh yeah, that might be a valid reason. But on that note, there are
different types of sockets. Apart from the cheaper ones, there are
turned pin sockets where each pin consists of a (probably milled)
solid part with a hole and a taper to a thinner pin. Picture linked
below. Those will solder fine from the top with a little effort and a
think tip. I discovered this type when I had made a homemade double
sided board and was expecting to use component leads as through-hole
connections. Nowadays, I mostly just don't bother with sockets. It's
not often that I've gotten a reason to either replace or reuse a chip
