(Lib)parted repairs the wrong partition types in all cases. In some
cases partman will not write the partition table but if it has to for
some reason then the partition type will be changed.

The kernel will complain that it can not reread the partition table.
This complain is not dangerous and partman can probably safely hide it
from the user but this already is not nice.
Moreover the confirmation dialog contains a list of the changed
partition tables. If we decide to write all partition tables to the
disk just because they contain some formatted partition this means that
they have to be included in this list. In most cases this list will
contain all partition tables and because of that it will be less
informative.
I think I can take the partition type from the structures of parted but
I wonder the format of these structures can change in future versions of
parted.

Yes, of course.
