In our processes, we have a sales person but we also have client support staff. Once converted, the lead needs to be tied to someone in each of those roles (for both notifications and reporting). At this time, as soon as someone else takes over the conversation, we've seen the contact reassigned to the other. Right now we have a workaround with custom fields but it doesn't enable us to pull the reports we need and it makes things cumbersome in the system having what equates to unnecessary additional automation to keep up with.
