Another consequence I've found playing with my extended system
generator is that a few systems come up with a Star or a gas giant in
the habitable (or one of the habitable) zones of the primary
star. If these systems orbit a star it's usually a tiny Mx V companion
which contributes very little heat to the subject planets.

Cool...

For a planet orbiting a companion star I take the temperature to be
greater of the temperature gained from the companion and the
temperature provided by the primary. What that means is that in such a
system there will be many habitable worlds.

What would such systems look like in the real world?

Honestly your guess is as good as anyones right now, as that topic is under lots of discussion in Astronomy circles.

I have pondered a cluster of such systems for a campaign setting.

I ask because I dimly recall that in the Joss Whedon's Firefly 'verse
he dodged the question of FTL drives by having his setting be a system
with multiple planets and moons in the habitable zone of their
star(s).

I would think that such a system could be interesting but the
Traveller system doesn't seem to embrace such things. There is a
mainworld that has the system tech level, trade classification, etc.

The "Mainworld" system is the suggestion that stuck, in Book3 it was briefly discussed using the repersented system to generate further worlds in a system.

Does anyone have thoughts about better ways to represent such
systems? For example: A system with a small vacuum world as mainworld
and a subordinate F466nnn-t planet only registers as "Farming" and
does not make the system "Agricultural".

Not as a single line item which was the Traveller standard in the early days.

Recently I have been pondering a different system creation system, using the standard system for generating the number of Belts and Gas Giants then adding a 1d6/2 rounding down with a minimum of 1 to describe the basic system. Then use the standard system to generate the "habitable" worlds. The other change is the Starport, which is changed to a Station in the cases Port classes A through C, D through X describing individual world ports (this is the part I am still working one)
