Mind sharing which two apps you went with?

When installing just two apps, even if both are in the same (KDE or GNOME) realm, you can very easily end up with 8 flatpaks (including runtimes) or more. This is due to a variety runtimes and their versions: One for KDE or GNOME Platform release (about two a year) plus a yearly freedesktop base) and not all apps being updated to the latest runtimes constantly.

You then have to add at least 6 locale flatpaks to these hypothetical 8 flatpaks.

Especially with Debian, locales matter, of you don't do a `sudo dpkg-reconfigure locales` and pick what you need before installing flatpaks on a default install, you will get everything and thus gigabytes of translations you don't even understand, wasting your disk space.
