Why does a project with product flavors not have the lintDebug task?

When I create an android project without product flavors and run ./gradlew tasks, I can see there is a lintDebug task. When I add product flavors

android {
    ...
    buildTypes {...}

    flavorDimensions "version"
    productFlavors {
        demo {
            dimension "version"
            applicationIdSuffix ".demo"
            versionNameSuffix "-demo"
        }
        full {
            dimension "version"
            applicationIdSuffix ".full"
            versionNameSuffix "-full"
        }
    }
    ...

And run ./gradlew tasks again, I only see lintDemoDebug and lintFullDebug, there is no lintDebug command. But there is still an assembleDebug command which builds both product flavors.

Why is there no lintDebug command that lints both product flavors?

Edit: The same seems to be true of testDebug. Why is this?
