Cargo storage can have more cargo than the limit. The troops just get added to the cargo area. Try building a Cargo Storage Facility, and then fill the planet with units. Scrap the facility, and all the units remain there and work fine. You can't add more, of course, and you can't just move one off and then back on.

Yeah, I see this nice feature also with an abbidon home planet with ex-extended cargo racial ability (proportions), it has now 18/15 facilities and I should better not scrap the cultural centers to free space for computer complex or similar.

I just fear a little chance of probably non-capturable full planets if this would be fixed because of a probably different combat cargo handling, probably like transfer from ship to planet. Most unlikely, but who knows.
