My thoughts, as it always scares me to think of letting anything run wild,
eventually they would become root bound and then think of the work to fix
that? ~ jan

I dunno. I have never done this before. What will the work be?

Last year many local ponders were invited out to a lotus pond that had been
an experimental trial as a food crop. So they hacked and they pulled and
they just got plain muddy. In the end I don't think anyone got those tubers
to grow, and if they did not for long, I think the tubers got hacked into
because people couldn't see what they were doing. Whereas a lotus in a pot
just has to be up ended, rinse off and you can tell tubers from runners and
cut in the right places. At least I managed to do that and both groups are
growing and budding, and I feel I have a brown thumb with lotuses.

Moral of the story: if they get root bound, and growth becomes pathetic,
when you try to redo you may have to rebuy. Plus, a potted plant is so much
easier to rearrange, remove, replace. ~ jan
