yes but there are still dependency problems if you want to install a
single package and you installed all the previous ones a year ago.
With PBIs each package is self standing, so you can install one
and not worry if it requires a different version of some library
to what you installed last year.

Yes but that is a worst case thing. We are talking about making
a system where the PBIs contain all the libraries needed but that
only some of them are installed, when there is not already the
same one (i.e. identical) installed by a previous PBI.
so if you installed, say, 20 PBI from the same 'set' you woudl only
be installing one copy of the libraries that

well no-one is going to make you use PBIs
