Any possibility to fix STM32F77xx bootloader flow?

I have found this note which says the limitations of STM32F77xx bootloader:

The problem is, the internal bootloader doesn't run the application by itself, and if I run it always from the application, what happens if the application crashes? how do I recover my board? I can not send a J-Link to every customer.

This is the same question than Tonny has asked and no one gave any support or explanation since September last year:

The latest Bootloader documentation (from this month) says the same limitation. Do we have any solution coming?

If yes, when?

Thank you

Yuri Rodrigues
