I proposed a separate extension called a "value holder" to the bugbox before it went down. The idea was that they are objects that can hold unlimited named values that could be re-arranged and come shipped with fusion like the standard array extension or backddrop. They would also theoretically be more performant than an active, since they wouldn't need to worry about being drawn to screen or collision etc. Being an "extension" would hopefully get around the core issues that prevent more than 26 named values currently.
Another hoped for feature of these was that you could also change the data type of these objects, so you could hold unlimited named strings or unlimited named flags, for example.
