In the backpacking and bicycle-travel community, titanium pots are widely regarded as good only for boiling water in, since they don't distribute heat as well as aluminium for more complex cooking.

I’m well aware, but I don’t really believe this :). As far as I can tell, no very thin pot or pan distributes heat well [0], and no very thin pan cleans up well from cooked-on food when the cleaning supplies at hand while backpacking.

[0] Concretely, this means that, when cooking solid food, the parts of the pan where the food isn’t sinking heat adequately get too hot.

The non-stick aluminium pans from MSR, and perhaps other brands, do clean up well from food after cooking. In my experience (hundreds of nights of cooking while cycling the world), it is enough to wipe them clean with a dedicated towel or wet-wipe in order to pack them, and then they can be washed completely the next time one reaches a convenient water source.
