But Traveller world populations are almost never distributed like that. Take Mora. The Mora system is surrounded by worlds with populations between 4 and 6, all of them utterly insignificant (as far as trade and taxes are concerned anyway). Two parsecs from Mora is Fornice with 20-29 billion people. But I say the odds are good that the two worlds are economic rivals and would very much not consider themselves part of the same political fraternity. And then you have Heroni in the extreme rimward/coreward corner, six parsecs from Mora and very much not part of any Morani cluster, and Pallique at the rimward edge, also six parsecs from Mora and also not part of any Morani cluster (I've not bothered to look at the pop 7 and 8 worlds). There is no informal border you can draw around a smaller Morani cluster that takes in all the important systems in the Mora Subsector.
Going the other way, you can't have two clusters in the same subsector that effectively answer to two different Imperial nobles, because any count of such a cluster would be a) not holding interstellar governmental authority in his own right, and b) subject to the subsector duke who would be very much interested in the major system(s) of the county.

I agree with a lot of that but that just makes it potentially more varied.

I'm not sure I agree with the first point entirely as in a lot of sub-sectors the alpha system dwarfs the population of the rest of the sub-sector on its own but I agree there are exceptions.

Looking at the 3I bits of the Imperial marches
(using my current trade map to illustrate the point)
https://gameystuff.files.wordpress.com/2015/02/spinward_canonports_routes_map.pdf
Glisten, Lunion, Rhylanor all more or less fit as the centers of a spider web cluster with lots of Firefly systems outside or in the gaps.
Vilis and Jewell the same but with a very small cluster part.
Trin also except the important cluster is concentrated in the upper part of the sub-sector with the Firefly part in the lower half.
#
The exceptions to the general pattern are:
1) Lanth and Aramis which don't really have a cluster at all
2) Regina / Efate where the natural alpha cluster is around Efate with a secondary one around Regina
3) Mora sub-sector which as you say has three alpha systems in the same sub-sector
4) the collection of B star port systems in between Rhylanor, Mora and Lunion.
#
So using the exceptions to provide scenery / potential plot hooks:
1) Lanth and Aramis systems being consciously built up / colonized to provide a hub for the sub-sector
2) Regina being consciously built up as a counter weight to Efate implying a bit of conflict there for Zhodani to exploit
3) Mora / Palique / Fornice as the center of constant political intrigue as the three systems plot against each other
4) Haven't decided on the fourth region yet.

Also it doesn't have to work everywhere. If someone likes the idea of a 1/3 Coruscant, 2/3 Firefly game then they can set it in one of the sub-sectors where it fits best.
