And then gnome-screenshot got crippled, but I managed to cope with that by patching it:
I'm using debian testing (jessie) on my laptop and since I normally don't do much on it other than occasionally log into work to check on jobs I have been able to ignore the issues that are so apparent in gnome 3.12, two of which are:
* gnome-terminal doesn't have a transparent background option since ersion 3.8 -- instead of being able to read what's underneath (e.g. a blog post with a how-to), and thus making good use of the screen real estate, my laptop screen is now feeling very, very small.
[And the developer seems to have the usual gnome attitude issue: https://bugzilla.gnome.org/show_bug.cgi?id=698544 ]
* you can't resize 'native' gnome programs, such as nautilus, that are in full-screen mode. Well, you can -- by holiding super (i.e. windows button) + down arrow. But the icons in the top right corner are no longer, and I find that incredibly annoying.

Image resizing is a different matter since we maintain our own little website with personal photos for overseas members of our families. Ergo, it's crucial.
Luckily, this is pretty easy:
sudo apt-get install simple-image-reducer
Go to Edit/Configure custom actions... and set command to simple-image-reducer %F, and scope to apply to images, as shown in the screenshots.
I'm sure there are lots of other small issues in gnome 3.12 that I either keep missing or wilfully ignore in the interest of maintaining a low blood pressure. The whole idea of removing features that are actually useful with no way of re-enabling them smacks of 'we know better than you', and that irks me.
