Comment 2 for bug 1918305

Strangely, important tag is not specified in the Ubuntu's source package, and actually that downloaded source package is completely identical to that of Debian Sid:

  $ grep -nr important hirsute/mobile-tweaks-3/debian || echo "Not found"
  Not found

  $ diff -qr hirsute/mobile-tweaks-3/ sid/mobile-tweaks-3/ && echo Identical
  Identical

The binary packages built from that downloaded source package have priority set to optional:

  $ cd hirsute/mobile-tweaks-3
  $ fakeroot debian/rules binary
  $ dpkg-deb -I ../librem5-tweaks_3_all.deb | grep ^Priority
  Priority: optional
