We had problems with them routinely, that's why I disabled alpha checkers in clang-tidy completely. I don't think there should be a user-visible way to enable them. Developers can locally change the code to get access to alpha checkers, but released binaries shouldn't provide this possibility.

Yes, a comment to that effect near the relevant code wouldn't hurt. Or do you have other suggestions?

As discussed with SA folks, alpha checkers are convenient for them to develop new checks, but shouldn't be exposed to users. Some of these experimental checkers might deserve being moved out of alpha or removed completely, but that should be reported to and discussed with the SA maintainers.
