F1 isn't meant to be relevant. A large part of the attraction is that it's spectacularly irrelevant.
Which of the teams agrees with you?
Mercedes and Renault apparently don't. Neither does Ferrari.
Mercedes and Renault seem to believe a smaller displacement engine would not only benefit their business, but would also be a draw for other manufacturers to enter the sport.
Ferrari opposes smaller engines for much the same reason: it doesn't see them as helping market its high-power brand.
It's certainly not my place to say that they're right or wrong. But manufacturers who are currently involved in F1 seem to believe that engine displacement (and the hybrid engine) could have an impact their business, be it positive or negative.
