Shrug just about every service I want to run has an official image. I use a couple unofficial ones (e.g. Minecraft, and I think my Samba container—oh man, talk about being easier to configure than typical distro packaging—is unofficial) for my personal use and it's pretty easy to read the Dockerfile and build them myself, so that's not a big deal. At work, most any database or self-hosted service or anything like that has an official image.

So yes, it is.
