Hey @DLKR. I assure you we take building Ghost very seriously. Every feature and addition made in Ghost is done with consideration and the community in mind on GitHub https://github.com/TryGhost/Ghost. Strikingly and WordPress have suffered the consequences of adding every single feature that people have requested, causing them to be bloated and overly complex.
I can understand why you want to align size the image, but we can justify changing Ghost just for a single case for a single user. Especially when it can be achieved with a little custom HTML.
I just went onto one of my demo sites, installed London, and created a left aligned image with the following code:
<figure class="kg-card kg-image-card" style="
<img src="insertImageUrlHere.jpg" class="kg-image">
Dropping that into a HTML card with the URL to the image you want should achieve the image presentation you want
