Better understanding of azdata.tasks.registerTask()

[dfalso]

2 questions around registerTask():

Based on the index.d.ts file, I would expect that I should write this:

    azdata.tasks.registerTask(
        this.registerMenuActivationPath, 
        (profile: azdata.IConnectionProfile, ...args: any[]): any => {
            <stuff>
        }
        );

I would expect that the profile parameter to be of IConnectionProfile,, but it isn't. I end up having to write this:

    azdata.tasks.registerTask(
        this.registerMenuActivationPath, 
        (e) => {
            const profile: azdata.IConnectionProfile = e.connectionProfile;
            <stuff>
        }
        );

I'm sure I'm missing something, but not sure what it is.

I see that azdata only has the tasks.registerTask(), while vscode has registerCommand, registerTaskProvider, etc. Should my extension always use azdata.tasks.registerTask() for everything? I've only registered against the dashboard and menu so far.
