The ability to use good prime lenses was also my excuse to buy a new mirrorless, and occasionally to put on a zoom for distant wildlife. My old DSLR was just to bulky so I left it home more often than not, the mirrorless is just that little more compact and light (especially with a pancake lens, it almost becomes a compact). And good prima doesn't have to be new and expensive btw. You can buy adapters to fit almost any old lens to any modern camera (especially with mirrorless). Only thing you will be missing is the autofocus and auto aperture control. But for me this adds to the experience, since you must really be engaged with taking the picture (eg, thinking about exposure, zooming with your feet, predicting when a moving object will be in focus), instead of having the camera do it's best (or worst) for you and fixing it in post with software. I have settled on a Fuji as their controls connect more to that feeling of manual photography, making the experience more fun for me. For everything else, my phone camera with cracked lens is good enough.
