This is why we have major and minor version numbers in hudinfo, as well as
'extentions'. I will not allow anything to break old clients unless we
really really have to. I'd rather create a new command that displays the old
information in a new way, and keep the old command.

That said, keep in mind that the spec says specifically what to expect and
what _not_ to expect. Do _not_ rely on the number of elements in a
list-like response; the addition to 'hudinfo t' should not break any
correctly written clients, even though to be more future-correct it should
up the minor version number or add an extention flag.
