Can modern derailleurs be used with friction shifters?

DER's are mindless robots.
They move as cable pull tells them to.
Indexing (or not) is in the shifters.
The only thing with older DER's is that they weren't designed with a specific cable pull to movement ratio.

There are certain designs that favour indexing and some older dérailleurs will not index well but every modern dérailleur will work just fine on friction although with 9-10 speed drives your shifting skills better be well developed as the throw becomes very short.

yes, they can but, if you'r runniing more than 7 or 8 gears in back , it's really hard to find and "center" a gear properly. Kinda like tryiing to adjust a spoke nipple with a ten inch crescent wrench

I was reading in a thread the other day, someone likes suntour barends for 9 speed drivetrains because there's no slapping chain on gears.. he said something to the affect of because of the tighter spacing, it just goes right onto the next gear.

I just set up a bike with the Shimano specific shifter bosses with old shimano friction shifters, a 7spd cassetter on a 8+ freehub and a Campi Veloce RD. After a bit of practice it shifts like butter. Well sometimes cold hard butter but butter.
Please ignore the shiny copper bell it has been replaced with a nice subdued black one.

Another modern feature that makes friction shifting much better than it used to be is the shaped teeth and ramps that make indexing work so well.

I have two bikes with ramped 7-speed cogs in the back and both shift just fine with Suntour Barcon friction shifters. I have a 9-speed cassette I'm going to try at some point, but I haven't gotten around to picking up a 9-speed chain, so I can't comment on 9 speeds.

As I went from 7 to 8 and then 9, shifting got more precise.
I think it was more of a matter of ergonomics between my thumb shifter and thumb.
7 speed I'd push and then have to push some more.
8 not as bad
9 was just a push 95% of the time.
My friction shifting went down the tube when I got a 2nd bike with trigger shifters.
