It’s a merged pull request made by a member. Dunno which release it’d be in. This means people can double-click deb files to install again (with a warning).

I can’t believe people construed the lack of this feature in a brand new software as bad Canonical want to kill deb! It’s a brand new software. Features need work. Either go and write them or wait for someone else to do it.
They removed installing another package that did this by default in the same version where they introduced the App Center. Ubuntu Software never handled installing third-party debs, gdebi did. And in the version where they introduced the App Center, they stopped bundling gdebi by default.
Also, the old behavior was that you double click on a deb file and App Center just hangs. This was shipped in the LTS.
