Unless maybe if they're racing, that doesn't make much sense to me. In some cases friction levers can mean more time between deciding to shift and making the shift, but that's not a significant issue when you can anticipate.

The aspect where vintage bikes can circumstantially suck the most is gearing range. 40" used to be a common granny gear for "wide-range" 2x drivetrains aimed at "recreational" cyclists, but these days, even pros occasionally tap into lower gears than that. High gears usually lie around 100 inches, which isn't usually quite as harsh of a problem... but it can make it harder to rest on the fast group descents, and I have spun out the back of a paceline before on a 100-inch gear.

Secondly, weight. Not usually an astronomical difference, but a constantly-present and measurable one. Add a few pounds to your bike and do a 1000-foot climb, and you might find it takes a couple tens of seconds longer. Many folks in many circumstances won't care, but it can be relevant on a Strava leaderboard.
