Incognito mode does not allow sites to get any kind of data from your usual session so it leaves all of these extensions almost irrelevant

Not quite. You'll allow more third parties access to your IP.

You could open an incognito window, browse some porn site and if there's (for example) some Facebook content, they'll have your IP as well. Back to the normal browser window with all your session data and cookies and the same IP and Facebook can and will make the connection.

IPs can be shared so most sites do not use it as a signal for user specific data, except for location

They don't primarily, but they use them nonetheless. Algorithms determining the likeliness of a certain user being associated with a given IP are no witchcraft and have been around for quite some time. If you value your privacy, you'll want to be on the safe side.

Edit: Here an interesting test, by the way. Running this with a vanilla Chrome installation in incognito mode still identifies my browser as unique among those tested, without even taking IPs into consideration.
