Your mention of 'alternatives' makes no sense to me.

The alternatives symlinks are not (and should not be) part of the 
package, but created or updated by postinstall scripts.

(It seems like it's impossible to make them work sensibly otherwise, as 
the link would be that from the most recently installed package (which 
could be any of the parallel installable alternatives), not the highest 
priority one.)

I don't know what this refers to.  Can you give an example?
