Bug#983892: libpetsc64-complex3.14-dev: leaves alternatives after purge: /etc/alternatives/*petsc64*

I'm looking into this problem. It's not immediately obvious where the
problem ultimately lies for this reason: the petsc64 scripts have been
constructed by analogy (copy&adapt) with the correspond petsc
(petsc32) scripts.

The prerm scripts have been configured to remove these alternatives.
At first scrutiny, libpetsc64-complex3.14-dev.prerm seems to be
addressing the alternatives in the same way as
libpetsc-complex3.14-dev.prerm (apart from handling some old legacy
alternatives which shouldn't be affecting
libpetsc64-complex3.14-dev)

If libpetsc-complex3.14-dev is uninstalling cleanly as intended then
why would libpetsc64-complex3.14-dev not be doing the same?

Likewise, libpetsc64-complex3.14-dev should be behaving the same as
libpetsc64-real3.14-dev.  Why is this problem only occuring with
libpetsc64-complex3.14-dev ?

If anyone can spot the difference then I'll be happy for the help.
