SPL reinstatement

Since it is hard to reach right people via email, and where are few people from STM software development group, i decided to write here.

How many people need to sign a petition for STM or something like that  to create SPL libraries for new STM32F7 and STM32L4 micro controllers ?

STMCubeMx in theory should be a great tool, but with SPL many of us could make complex task work in mater of minutes, and right now at least for me, it is just unexplainable, how i can't do simple task, with no reasons why ( maybe it's new IAR ARM compiler at fault?)

simply by changing order of TIM_Config() for simple PWM could mess up my EXTI config for completely different pin group, this is just crazy. Not to mention random crashes and so on. I spend this week trying to port F4 code, and so far, only led function is working.

Also, by copying examples from stmbubef7 it does hang in assert_failed loop, while i know that i can get over 200MHz legally, same goes for many many functions.

also, HAL uses Systic for delay function with no easy way out. but what if my program is so DSP loaded, that interrupt at wrong place could make my program glitchy ? ( i am running DCMI with camera at  56Mhz + using DMA to stream data to computer at 10Mbps + running PID loops on processor itself. i can't get systic interrupts, because processor will be overloaded and miss lines of images, and stuff like that.

So the question is, how many people should ask for STM to produce SPl libraries for F7 series ?

Because at this point, i was using only STM32 parts for mid to high complexity projects, but due to HAl libraries, i am thinking to switch to other parts, and i read same thing from others. I i can't make simple program work in a week, while with STM32F4 could do same think in few hours, you know what i am thinking...
