I don't know about that, I happily use it to host a couple of Wekan and Dokuwiki instances, and some random Etherpad docs. It's certainly MVP-complete.

And even in its current state, it has some fantastic affordances that I don't feel I could get anywhere else.

For example, I had an instance running on my laptop to fiddle around with developing apps. I wanted to take a Dokuwiki on my laptop and move it to my cloud-hosted instance. I clicked "download backup" of the grain, which gave me a zip file which was whatever, 40MB or something, and then I went into my cloud setup, clicked "import from backup", and voila - my entire Dokuwiki grain was now in the cloud.
