I don't know if you have tried single SM and if it that is the case, you must not have tried in the best conditions.
People who use "counter-balance" weight system are also not diving with the proper set-up.
With a S80 or stell 10L (72cf for you I think), you don't need any ajustment.
My wife and I, we have been diving rec that way for years and it is a no brainer.
Travelling, we take a bungee for the top and a d-ring we will put at the weight belt we get at destination and that is it.
We also have a Deco wing and a modified MSR bag if the conditions call for it.
We wear 3min or DS. For 3min, no weight needed (but sometime I take 2kg with a S80) and for the DS, enough weight to sink it. After, we all have an integrated BCD which it called "lungs" and that is enough :)
Yes vintage diving is also really good and really minimalist but frankly single SM is not unconfortable at all but of course YMMV

I tried this in a pool recently (sans exposure protection) because I think that sounds fantastic for travel. It works, but with a full AL80 I still list if I entirely stop moving. That lessened as I drained the tank somewhat, and I expect I'd spin slightly in the opposite direction with an empty, depending on net buoyancy of tank + 1st stage.

I love rec sidemount, but specifically for its balance and stability, and that seems to be somewhat absent with single tank. I used to dive single + DS, but there at least you can move air around in the suit to compensate, and if I'm traveling with my DS then I can probably fit a full harness as well.
