Any feeling how best to do that? My current thinking is to export a "flags" entry in addition to the current ones, presumably based on "struct parsed_partitions->parts[].flags" fs/partitions/ check.h), which seems to be what causes md_autodetect_dev() to be called.

I think I would prefer a 'type' attribute in each partition that records the 'type' from the partition table. This might be more generally useful than just for md. Then your userspace code would have to look for '253' and use just those partitions.

Well, for an MSDOS partition table, you would look for '253', for a Mac partition table you could look for something like 'Linux_RAID' or similar (just arbitrarily define some name beginning with the Linux_ prefix), etc. This means that the partition table type would need to be exposed as well (I don't know if it is already).
