Tarmac is not going to stop you if you have a brake failure unless you have a lot of run-off area, but it is going to help you if you make a driver error. There is a chance that gravel will make you airborne, but it will slow you down faster if you are going slowly enough. A balance needs to be found between safety and punishment and at the moment its leaning too far towards safety, one of the biggest problems is all these new circuits have ridiculously massive long straights which means there has to be lots of run off. Just look at India, Korea and Abu Dhabi, all of them have massive straights, doesn't do much for overtaking (without DRS) and hence leads to massive run off zones and therefore a lots of tarmac, make the straights shorter add more corners (not 90 degrees) and then you can add gravel for punishment if a driver goes wide.
T1 concern is not brake failure. That turn is taken at relatively high speed with only medium braking. The tarmac is there so driver has chance to recover if he makes mistake or if the back of the car gives away causing slide. Not to mention in stock car races the car is heavy enough for its momentum alone taking it wide in that corner. The tarmac there gives better chance of avoiding injury to driver in case of mistake as it is relatively high speed corner with more than moderate elevation change.
And this is a balanced solution. There will obviously be a instant penalty if driver takes advantage of this runoff to gain position or time like it is on other circuits where you must give back position if you cut the chicane. The current concern was proximity of the wall next to such high speed corner.
This circuit is still very flowing circuit. The speed is result of not just straight but the momentum carried right from juncao exit which slingshots the car on the start straight.
If you put gravel or grass there, the extra space will be actually more deadly than help in any way for safety. This is the only practical solution without making changes to actual track layout. Putting gravel trap there would be as dangerous if not more than having a wall there.
This solution actually preserves the flowing nature of the track. The other solution would have been to put a chicane there which would have totally ruined the circuit.
