The booster landings are all lumped together, but they all have very different parameters. They've never failed a landing on land. and since they succeeded at sea, they've only failed once since then, and that was coming in from GTO, which is borderline not possible by their own admission, they only tried just to get more data points. The upcoming Echostar 23 mission is flying in expendable mode (no landing attempt) because the mission parameters simply don't allow for a landing. They could try and fail, but they don't really need more data points - especially when people don't realize that these experimental landings are just experimental, and it winds up with bad press. spacex does walk a fine line between "rapid development causing potential issues" (see AMOS-6) and "abundance of caution" (see CRS-10 delay on saturday)
