When parametrizing, I will not have the same number of line features depending on whether I radius a corner or not (as well as other conditionals).  It would be easy to add line elements to an array and then form the line loop with those, I don't see how to do it otherwise.

Sure, just construct an array with the IDs of the points/lines you want ; see e.g. tutorial/t5.geo where a surface loop is constructed this way.

There are many useful operators on lists, e.g. += to append or -= to remove. The "Boundary" and "CombinedBoundary" operators are also often useful to automate boundary generation.
