If I blindly follow the rules written in Chapters 5.3. and 5.4., I end
up in the situation I described earlier -> handover (rules 5.4.1.2 1 and
2). There is no explicit requirement (following the rules in the
specified order) that if HI=5, the PBU must include all the session
parameters or at least none that I could fine.

I agree, it's not big of a deal; the binding in LMA will be updated
properly if the decision is either 'Binding Lifetime Extension- No
handoff' or 'Binding Lifetime Extension - After handoff'. Moreover,
tunnel and route setup functions can easily see that such routes and
tunnel already exist.

Regz,
Tero
