That's a good question. However, for such an important system setting, I do not quite like allowing arbitrary options that are not thoroughly validated by tests. The annoying thing here is that I can imagine the system easily breaking (now or in the future) in subtle and hard-to-debug ways when you get unlucky with your selection. (For example, you would need to know that using '#' as a delimiter, while maybe decent-looking at first, is a pretty bad idea because it clashes with the namespace prefix character)

That said, I'm not opposed to adding more options; we could consider '|', ':', ',', '\' (any more suggestions?) But we have to be aware that any character added to this list might need to be handled with increased care going forward.

> Currently, we use '.' as a constant hierarchical delimiter for mailbox folders.
> We believe this to be a suboptimal choice and think using '/' would serve better in general; however, changing the default is not desirable because it would break existing deployments. For this reason, we propose to add a configuration switch enabling to select a delimiter out of a list of suitable options (only '.' and '/' for now, with '.' being the default).
> This might also aid with #3545, where '.' as a delimiter is identified as a problem for JMAP as well.
