Next I would like to address automatic partitioning restrictions with
software RAID arrays, see for example Bug#1146054: partman-auto:
Detection of fakeRAID is flawed [1]. Any opinions ?

I fear I have some disadvantages on this fakeRAID topic:
I have no hardware for testing IMHO (?),
and no knowledge, how common this fakeRAID path is these days.
AFAIK, platforms which support IMSM are:
- Intel Matrix Storage Technology (IMST) on SATA - EOL.
- Intel Rapid Storage Technology (RST) on SATA - EOL.
- Intel Volume Management Device (VMD) on NVMe - current.
- Intel RAID on CPU (VROC) on Xeon + NVMe - current.
It should be mentioned in BIOS/UEFI options or boot screen. Even though,
no need for specific hardware: an IMSM container and volumes can be
created and used on SATA (and maybe NVMe) drives on any amd64 physical
or virtual machine in d-i with a small adjustment.
Regarding how common it is, the only use cases I can think about are:
- dual boot with Windows on the same drives
- seamless redundant UEFI boot
