With debian stable, packages get stale and or rot. For instance there is a very annoying but in qbittorrent that has been solved in a later version. The later version is included in bookworm/testing. My question is, if I change /etc/apt/sources.list to say ‘testing’ instead of ‘bullseye’ and then apt update && apt upgrade && dist-upgrade, are things certain to break?
Generally yes, but some things do not yet work correctly. See some testing and tasks in our Wiki: Debian Bookworm testing · MichaIng/DietPi Wiki · GitHub
We do provide Bookworm images already for most devices, for testing purpose: Index of /downloads/images

Thank you for the info! I’ll give the bookworm images a go. I’m generally comfortable with debian testing and it’s quirks… Debian testing has been my daily driver both at work and home for the last 2 years or so…
Is there an arm version that will generally work best? v6, v7, or v8. All are compatible with my Pi3.
Jep, I use Bookworm as well on all production systems. Just need to accept that breaking changes in Debian packages are possible and hence some manual changes and changelog reading necessary by times 
.
Nowadays I recommend the ARMv8 (64-bit) image for all RPi models which support it, unless you require a specific software title which is not supported on ARMv8 (resp. an arm64 Debian userland). But should be rare.
