Pitivi 0.97 is available, but the most recent version Trisquel 7 will give me
from the repos is 0.93. Pitivi support the use of Flatpak to allow me to
upgrade to the latest version in this situation:
http://wiki.pitivi.org/wiki/Install_with_flatpak
But Trisquel 7 doesn't have flatpak. So I either have to install a PPA for
Pitivi, or a PPA for Flatpak. Flatpak seems like the better option, since
this will allow me to install the latest version of any project that supports
the use of Flatpak like Pitivi does, rather than adding a PPA for every
project. But I'd prefer to be installing PPAs at all. Unless there is an
ethical concern or a proven security problem with Flatpak, I think it makes
sense to include support for it in Trisquel 8.
By all means include support for Snap and GNU GUIX too, it's good to have
options. But really, the choice is made by the project doing the packaging
(eg Pitivi has chosen Flatpak), not the user. Unless anyone here knows a way
to use GNU GUIX to work with Flatpak or Snap packages?
