Is it possible to combine router.js and maintainer.js for v2 routes?

I have contributed to a few issues and got this idea. If I add new features to a route by adding new parameters into the route path in router.js, without updating maintainer.js at the same time, then the route path in these two files won't match.
For example, one route is /user/dynamic/:uid/:disableEmbed?, and I add a showEmoji parameter. After this, the path in router.js is /user/dynamic/:uid/:showEmoji?/:disableEmbed?, but in maintainer.js it is still /user/dynamic/:uid/:disableEmbed?.
So I wonder if combining these two is a good idea since they share the same path strings. If possible, I only need to modify the path once while adding new params.
