Almost. Ramps and pins are essential for good index shifting. Ramps and pins noticeably improve friction shifting.

I have an old Trek road bike I use as a beater. It originally had an SR triple crank with plain flat chainrings and barcon shifters (friction in front of course). Shifting even from large to the middle ring was not very precise and was very sluggish under load. I replaced the SR with a Shimano 105 triple and, using the same barcons, front shifting is worlds better.
