Adjusting backstay helps control mast bend, prevents foresail luff from slackening if the mast is bending in the wrong directio, prevents mainsail from losing drive because mast is no longer in the shape the sail was cut for.
Cunningham tightens luff, removes potential for wrinkles, which spoil the shape of the mainsail.
Also, as I understand it, a Kevlar sail does not have zero stretch, it has some but very little, so you still have to control that by pulling the luff and foot to the correct tension.

That is called Rake, it makes a difference in High Performance/Racing.
Forward Rake is normally used on most race vessels, on some the Backstay is used to adjust that, in conjuction with the Forestay it can add a good bit of speed to a vessel.
All depends on the vessel, it makes a difference, assuredly.
That is known as Rakeing a Sail.
