Bicycle Mechanics - Removing front barrell adjusters - Improves shifting?

I was at my LBS dropping my bike off for service. I told the guy that I had put the grouppo on a couple hundred miles ago and needed a tune up. My thinking is the cables have stretched out as they should. The tech said he would take a look and also suggested that I don't need the barrell adjusters on the front of the bike, coming from the hoods as in the picture below. Will taking these adjusters out of the picture give me better shifting?

He goofy, the barrel adjusters are not compressable,if the adjuster is out to its limit, screw it back in,
and take the slack out at the derailleur end.

there is an adjuster on the rear deraileur, so it is likely redundant.

But none for the front derailleur , just taking ths slack out of the stretch may be good enough..

better ? the mech has taken the skill out of the rider , and made it a mechanical process.

getting the clicks in the front and the movement of the rear mech synched
is better done hanging the bike up so you can see the results of the adjustment

It is rather a reach to the front of the bike,.. the barrel adjuster on the RD is there so you can see it's effect.

If there is also a set of barrel adjusters on the head tube, I could see the redundancy. However, the in-line adjusters really shouldn't diminish performance.

They don't affect shifting in any way, as long as the cable isn't rubbing against the outer shell. Then you need longer housing.

Multiple barrels give you greater range of adjustability. I never worked on a road bike, I am a MTB guy, but I believe that cable housing won't sit snuggly into the flange which is designed to be used with a barrel.

Screw that barrel back in and tell that guy to quit his job.

How could it possibly improve shifting to remove the adjusters? I like having barrel adjuster on both of my shifters. I can fine tune my shifting while riding which is the ultimate in tweaking.

If all the guy said was you "don't need" the barrel adjuster, he is technically right. You also don't need a rear brake, handlebar tape, multiple gears, or a front shifter at all, for that matter. Removing the adjuster could only change performance if the adjuster was somehow causing friction as the cable slides through, but they generalyl do not cause any friction.

Leave the adjuster in there so you can... adjust!
