+>>> Bellow is my reasoning.
+
+>>> In one of my own real world examples, my two main use cases are :
+
+>>> * the "full-blown example" provided in the documentation (i.e.
+>>> displaying every parent but mother and grand'ma as a group, and giving
+>>> every of these two last ones their dedicated div);
+>>> * skipping the two oldest parents, and inside what's left, displaying the
+>>> three youngest parents (i.e. mother, grand'ma and grand'grand'ma), each
+>>> one with a dedicated style;
+
+>>> Both of these can be achieved by combining `PEDIGREE`, `DISTANCE`, and some
+>>> CSS tricks to hide some parts of the list. `IS_MOTHER` and
+>>> `IS_GRAND_MOTHER`, as well as `PEDIGREE_BUT_TWO_OLDEST`, would be convenient
+>>> shortcuts, but I do not formally need them.
+
+>>> So... it seems things can be simplified greatly:
+
+>>> * I initially added `RELDEPTH` for completeness, but I'm not sure anyone
+>>> would use it. Let's give it up.
+>>> * Once `RELDEPTH` is lost (modulo Git tendencies to preserve history), the
+>>> known bug is gone as well, and `PEDIGREE_BUT_ROOT` and
+>>> `PEDIGREE_BUT_TWO_OLDEST` are now only convenient shortcuts functions;
+>>> they could as well disappear, if you prefer to.
+
+>>> It appears then that I'd be personally happy with the single `PEDIGREE` loop
+>>> (renamed to `PARENTLINKS`), providing only `PAGE`, `URL`, `ABSDEPTH` (maybe
+>>> renamed to `DEPTH`), and `DISTANCE`. This would make my templates a bit more
+>>> complicated to write and read, but would also keep the plugin's code to the
+>>> bare minimum. Let's say it is my up-to-date proposal. (Well, if the various
+>>> shortcuts don't really annoy you, I'd be glad to keep them ;)
+
+>>>> This sounds fairly similar to what I just described above. (I called

+ <TMPL_VAR NAME="PAGE">
+ </a> /
