I believe that's correct. However, MacPorts does record whether you requested a port (by running "sudo port install X") or whether the port was installed because it was a dependency of something else. You can use the pseudoports "requested" and "unrequested" to address these sets of ports (for example "port installed requested" and "port installed unrequested"). You can use the commands "setrequested" and "unsetrequested" to change these lists (e.g. "sudo port unsetrequested Z"). Ports that are both unrequested and are not currently needed by anything else are called "leaves" (e.g. "sudo port uninstall leaves").

I know of no plans to discontinue universal variants in MacPorts, and I would be opposed to such a change if someone were to propose it. There is not a separate universal variant buildslave, however if universal versions are needed by default (as is the case for wine) then the buildslaves will build those.
> Good to know! :) A bit curious then that (I think) I've seen universal variants for older versions (and/or other OS versions) of certain ports. But that's maybe just because it takes time for new versions to be built and permeated throughout the mirror network and/or there's a certain feedback concerning what ports are being installed?
New universal versions of ports would only be built by the buildslaves when a port requiring them (such as wine) has a change committed to it.
