I'm using it since it was launched. For my use case, it lacked the ability to use a different container for a page based on the entire URL, not just the domain. For example, I've certain GitHub orgs that I'm using a separate account for. So the built-in ability to open sites based on the domain does not work for me. I found the extension containerise [1], which offers the ability to assign containers based on globbing and/or a regex pattern. It's not something a typical "normal" user would need, so it's reasonable to not include this kind of feature in the built-in account container implementation.
