I don't think it's correct to expect any hardcoded limit.
The struct parsed_partitions->parts is allocated according to
disk_max_parts() where the limit depends on number of minor numbers or
it's DISK_MAX_PARTS (=256).
There is no problem to create disk with many partitions:
# modprobe scsi_debug dev_size_mb=300
# (echo -e 'g\n'; for i in {1..100}; do echo -e "n\n\n\n+1M"; done; \
echo -e 'w\nq\n') | fdisk /dev/sdb
# lsblk -n /dev/sdb | wc -l
101
Note it's fdisk with GPT support.

Cool!
