In its present form, it does not produce many reports, so it might be worth waiting for patches like D49360 and D49361 that add more functionality.
A recent run on LibreOffice showed one report by this checker, and it seems like a real bug (in an external package called GPGME).
Can be seen here, or if it does not work, line 135 here (quite a one-liner).
@rnkovacs Personally I'm fine with moving it out of alpha then.
If all the reports you have seen so far are true positives, then it's *amazing*.
I would even go as far as filing bugs on the projects in question (as a by-product, it generates visibility for you, your checker, and the analyzer) but of course it's up to you.
