We just designed out similar LGAs made by Linear when a reliability analysis showed VERY EARLY failures probabilities for our typical operation cycle over a 20 year life.
You can certainly get them soldered and have them pass a screen but that may not be the whole picture. Depends on your operating environment/life requirements. Suggest having someone who is good at analysis run the numbers.

Subject: [TN] LGAs in a military environment?
Hello Technet!
One of our designers is advocating using a LGA component in a military
product. Anyone out there doing it? I'm wondering (worried) about the
reliability since it has a very low standoff. And cleaning issues?
An example of the parts I'm referring to:
