I'm sorry if what I said implied there was a rule to that effect. I should have said, "We tend to prefer the fuller form."
As you say RDA says all things being equal choose the shorter form, "if it is sufficiently specific to differentiate the body." Often these acronyms or shortened versions are not particularly, or in some cases, remotely identificatory. For example:
International Conference on 3D Imaging, Modeling, Processing, Visualization and Transmission
IEEE International Conference on Vacuum Microelectronics
(n.b. examples picked more or less at random from IEEExplore to demonstrate a point; I have not necessarily done authority work for these two conferences.)
There are exceptions of course. If the sources of information use an acronym exclusively, or as sometimes happens the acronym remains stable from conference to conference but what that acronym or shortened form represents changes, then we may out of necessity use the acronym. Sometimes the shortened form takes on a life of its own, and what it originally stood for is dropped.

Ben, forgive me for responding to a question you didn't ask--and with another question, yet--but why do you say we prefer the fuller form? Other things being equal (forms found on equally preferred sources, equally commonly, equally (in)formally presented), RDA 220.127.116.11 tells us to choose a brief form if it is sufficiently specific to differentiate the body.
As for your first actual question, one could argue that if you feel the intention of the organizers was to drop the numbering, then you are not inferring that the conference is one of a series of numbered meetings.
My opinions only, not necessarily those of my employer.

In these cases, we prefer the fuller form. But do we qualify the shorter form in the 4xx with numbering taken from the fuller form? ...
