Having to build a subtable as large or larger than the main workpiece seems the machine equivalent of begging the question, LOL. If, OTOH, the subtable was any arbitrary piece of metal, not particularly true, and largely just there to provide a reasonably smooth sliding surface and a place to mount your leveling screws, that's another matter.

It was a length of flat bar, I did say you could
consider it a sub-table.
Your OTOH explains its purpose exactly.
The reason to not use vises was we didn't have any big enough, the part was eight inches wide. Also with vises the accuracy of repositioning is going to be limited by the accuracy of the outer edges of the part.
