I realise you are giving opencv as an example of why having Python to AHK would be desirable, but for anyone wanting to read GUI elements like buttons there is ImageSearch[1]:

Also, to make it even easier to generate AHK scripts to automate button clicks, clicker games, or boring tasks requiring the keyboard and mouse, you can generate an image recognition AHK script quite easily using Pulover's Macro Creator[2]. Even someone with minimal knowledge of scripting can use it to automate Windows.

Even without Python, AHK is amazing. It gets a lot of undeserved flak from advanced users, undeservedly so in my opinion.
