+>>> I think we can roughly split the needs into three categories:
+>>> 
+>>> 1. never display any modified page title in links; this is the
+>>>    current behaviour, and we should keep it as the default one
+>>> 2. display modified page titles only at well chosen places; that
+>>>    could be "manual" wikilinks, I mean those generated by the
+>>>    `link`, `camelcase` & al. plugins, the recentchanges page, and
+>>>    maybe a few other places; keep the usual pagename-based title
+>>>    for every other link, such as the parentlinks ones.
+>>>    The inter-page dependency problem remains, though. As a first
+>>>    step, I'm in favour of the "slow, but correct" implementation,
+>>>    with a big warning stating that enabling this option can make
+>>>    a wiki really sluggish; if someone really wants this to work
+>>>    fast, he/she'll implement a clever dependency handler :)
+>>> 3. display modified page titles all over the place; IMHO, we
+>>>    should implement only the bits needed so that the `po` plugin
+>>>    can set this up, rather than provide this as
+>>>    a user-configurable option.
