I've been involved in projects that take it a step further. They realise that two products or code bases are similar enough that they can be duplicated, like the example you've given above. But instead of splitting the code bases, they decide to have one code base, that codegens the code for both projects.

At first code gen this way seems ideal, but the trouble is you'll start to realise one project needs a feature that the other doesn't and or it needs something implemented in a different way. The code gen in question doesn't support feature flags in a straight forward way, and adding extra features comes at a cost greater than just writing code to do it properly. Then you'll have to start maintaining not only the two projects, but a proprietary codegen framework.
