Well yeah, that’s the scientific process.

Things have to be investigated and tested, even when they seem obvious.

Usually things turn out as expected, but you also need to remember - at one point it was “obvious” that bad smells caused the bubonic plague and that leeches could cure a wide range of diseases. Sometimes what we consider obvious is actually a load of shit.

Besides, reports like this can tell us how effective getting that support might be, if it’s feasible to do on a large scale, etc.
