Including other elements (decorations, workstations…) in the building limit is a good idea. Because it adds depth to the system and allows for a strategic approach. For example, you can hide workstations that you don’t currently use. Instead of leaving your mess to others…
Or, you can only focus on production or building rather than decorating - depending on how you like to play.
About 28 workstations are enough for the full game experience, therefore, the poll is mainly about building elements, containers and decorations.
You can find the full list of 28 workstations here: Further explanation >Details…>2. (expand Details).
If there were a hard limit, the best situation for me would be if each server had a different value for building limits and even companion limits. Everyone could choose the right server for themselves, just like choosing whether to play PvP or PvE. Some servers would have a double limit, others might have a reduced one.
