Restrictions depends on different ECS (pre or post MOD 30626), FWC standard and the aircraft type. Speedbrakes are related to the A319. Without all speedbrakes the AC is not able to get down to FL100 in time when the 2nd pack goes INOP.

A320 Angles
320:In manual flight: 40d for spoilers 3 & 4, 20d for spoiler 2.
I don't have an A320 QRH, but I assume AP OFF is not part of the Emergency Descent?
Even when speedbrakes are operative the A319 is limited to FL370 with one pack U/S

From a legality point of view there is no need to descend , as per the provision of MEL , as long as speed brakes ares operative. Airmanship might dictate otherwise depending on the situation , this is where captain decision comes into play and that's why robots haven't replaced pilots yet.
Similar question just to give food for thought . AC ESS BUS FAULT leads to the deactivation of cabin oxygen masks door ( Auto+manual are inop) and this is not even indicated in ECAM , just a little note on FCOM saying so. So now your pax don't have oxygen in case of depressuraziation.
Would you descent to FL250 ? Considering that your A320 has become an "ATR" , would you continue at FL390 because there is no "if scenarios" ?
Would you ask you your purser to use the Manual Release Tool to open manually all oxygen masks doors in the cabin scaring your pax , or would you stay quite and proceed to your destination?

Single bleed fault ECAM action and PRO ABN do not mention descent but MEL limits ops above FL315. So in case of bleed fault in flt. Would you descent?
As in all cases, you need to know the procedures but also have the knowledge to apply them effectively. A bit of airmanship and common sense is always required.
