My take: the main purpose of ebegin is to inform the user that we are starting a silent long-running task. eend tells you the result of that task. Buffering ebegin calls would sort of defeat that purpose of informing the user that something is happening. In other words, I don't think it makes sense to call ebegin before starting a task that is expected to produce output. This includes tasks that call ebegin themselves, since ebegin always produces output.
