While contemplating this I got thinking:

What are expectations if you get an INVITE with both Alert-Info and 
Replaces?

Normally one expects that INVITE/Replaces won't alert. I suppose that 
expectation is really local policy. And ISTM that it would be really 
unusual to put an Alert-Info with it.

And how does that relate to Richard's question?
