I use this on one of my servers for storing gpg encryped mails. I wanted to make a FUSE module out of it but was too lazy. Of course you do read the data at one point but on a different system.
yes, there is. Imagine yourself on an airplane on your way to doing that million dollar demo to investors. And some bozo decided to do a last minute change to log something inconsequential that actually started throwing an error. Now your demo page looks like "Oops! We screwed up!". You have no time to debug this. So you just plugin in this module and see if it still good enough for your demo. If it does, you saved yourself a million dollars. If it doesn't...
Git? We're hustling out our MVP to disrupt the industry paradigm, we don't have time for version control! Next you'll tell me hacking on our live server is a bad thing...
I'm kinda tempted to use it in a script I'm making to scrape one of my government's databases, because they have a lot of malformed data I don't want to deal with, and because fuck it.
Prototyping - you just made an interface change that normally would have to be plumbed though hundreds of files just so you can experiment with one of them.
