The downsides are an inability to fix the code later and an inability to access members of a private d-pointer class.  Neither of those are an issue here, as we're just renaming the method.

Well, I wouldn't bother about runtime penalty given that it's deprecated and we shouldn't be using it anyway. Also we can't make assumptions on how things are going to be optimized.

But it's ok, I don't think it's worth discussing further, I doubt this is going to be a problem in the future.

If the method is const (like a getter), there's no point having it a slot at all; if you want to be able to use it with invokeMethod, you can just make it Q_INVOKABLE.

Well, having const methods as slots doesn't make sense indeed, if it's not for exposing on the meta object system, that's why I said you could do a fast lxr. I just did, didn't find anything relevant.
