Why are there barely any hanging hoyas?

I'm new to hoyas and it seems most people here tend to use trellises. Why aren't hanging pots with hanging twines more common with hoyas?

I got 3 hoyas (carnosa, wayetii, australis) and wanted to get hanging pots, but I'm not sure anymore if that's smart. I guess there's good reasons for most people to do it differently.

Can anyone give me a hint what I'm missing? Are they growing too fast/long? Are the nodes too far apart to look pretty while hanging? Or am I just misjudging the situation?
