The UI for the router looked ok until 2.2.0. Now you start evolving backwards by implementing serif fonts from the end of the 90th. Why would you catapult the UI 10 years backwards and start implementing serif fonts?

It escapes me how this can pass the head of product. It look ok so far. Did you assign a summer vacation project to a working student? Why would you evolve it backwards? I just puzzles me. Taste is of course very personal, but who on earth is deploying serif fonts in the 21st century?

If it wasn't a working student, do yourself a favor and get rid of your UIX designer.
