Comment 4 for bug 1783600

Bumping standards version/adding b-d-i in upstream (will be in the next upload, I don't think the MIR will block on that, correct?)

For the gtk2 support, we need it especially for Qt applications. We discussed that in our team meeting and ubuntu-desktop channel and it doesn't seem that we'll demote gtk2 this cycle, so having the dep makes sense for this cycle.

Unfortunately, there isn't an easy split that can be done as of now (the issue being mostly Qt applications related), but something we'll revisit int he cycle where dropping GTK2 is one of our goal.
