Was parent unsuspecting?
They said they wanted 'more frequent updates even at the cost of a little stability'.
They sound like they're very much in the suspecting camp.
The challenge with Debian Testing is some security exposures are longer than for either stable or unstable, hence the recommendation to keep unstable in your sources, ready to go, and maintain some awareness around CVEs / DSAs.

I can happily disabuse you of that notion.
Definitely, you should not recommend Debian Unstable to unsuspecting people.
I have occasionally run unstable on one of my machines over the years, but now pretty much avoid it.
When it breaks you either wait for a few days for it to be fixed, or you spend a lot of time trying to understand what's broken - usually with a machine that doesn't get you to a GUI.
