Bayliss' side face West Indies over three Tests starting later this month, before heading Down Under for the Ashes, and the Australian is still a long way from being able to choose reliable operators to help shoulder the burden weighing heavily on Root and Alastair Cook.
England sensed series victory, and got over the disappointment of Jonny Bairstow being dismissed for 99, as James Anderson ripped through South Africa's first innings with 4-33 on Day 2 of the fourth and final test on Saturday.
"We've generally batted first on wickets that have done a lot for the bowlers".
In 17 balls, Ali had sent South Africa from 3-163-3 to 6-173 and the tourists were all but done. They have now scored just two centuries in their last seven Tests.
"It is a challenge for Vern because it's happened too often that he doesn't play a full series", du Plessis explained.
"I love what I see in Temba's character and he's going to be an important leader for us in the team".
"I just went on instinct, and backed myself".
"They are relentless and our batting line-up wasn't strong enough for them".
The former Pakistan off-spinner is, however, now employed by the England and Wales Cricket Board on a consultancy basis only and Ali said: "If you are going to have batting, fielding and fast-bowling coaches, it would be nice to have a spin-bowling coach for pretty much all the games".
Botham achieved the feat twice against Australia, in 1981 and 1985 - though both those series were made up of six Tests. Philander was excellent - when he was on the park.
Although still not sure if an approach has been made to Gibson, Bayliss did say that "it sounds like it" when asked if his bowling coach will take the Proteas job. He seemed equally able to hold up an end and concede less than two runs per over or attack the batsmen.
Ali followed up with his 20th wicket of the series, surpassing his previous best of 19 at home to India in 2014, when Keshav Maharaj was plumb lbw.
Meanwhile, Olivier only played two Tests but improved with every spell that he bowled.
"I believe England's players are good judges".
Where to go from here?
Root's first series as England's Test captain ended with a convincing 177-run victory in the fourth Test at Old Trafford. The Faf du Plessis-led side limped to the close on 220 for 9, still trailing by 142, with Kagiso Rabada's last-ball dismissal summing up their futile situation.
"The change with Quinton going in at four was to transfer pressure back on the England team - he is the one guy who can do that".
England were all out for 243 to leave South Africa needing a near-on impossible 380 to win.
