There is some testing that is done against a set of projects on
code.dlang.org, though I get the impression that it's not very reliable (it
frequently seems to fail due to reasons unrelated to the PRs being tested),
and for better or worse, it doesn't have to pass for something to be merged.
So, even if std_data_json is on the list of projects being tested, I'm not
sure that it would have helped much. I don't know if std_data_json is on the
list though.

CI stuff like that has been improving, but there's still work to be done on
that front.
