When I was younger and had much better eyesight, I used to do an
excellent job with just a fine tipped soldering iron. The OP in that
forum managed to get by with the same.

Soldering in, yes. But it is neraly impossible to de-solder these.
With a lot of patience, even that could be feasible with good
standard soldering iron. However the risk of breaking off pins
is pretty high, as you will have to de-solder them individually.

Blowtorch or hot air gun on other side of board. Turn board over, part
falls off cleanly.

Risky with the typical thermal contraints. May work though.
