Updated Categories API now missing categoryTypeId

Question

I'd be very interested to understand why the BC development team has suddenly removed the categoryTypeId field from the API results.
I applaud the new update/delete capabilities, but this field removal has thrown a spanner in my works.
Basically, the CategoryTypeId field indicated the "level" of a particular category in BC. (42= Level1, 43=Level2, 140=Level3, etc.)
(As an aside, I'd be curious as to why 42, 43 and 140 were chosen as opposed to say, 1,2,3... but I digress.)
Anyway, I was using that CategoryTypeId field to create a set of "cascading" category selects as shown below:
(i.e., You select a directory from the first select and the second select appears containing the next level of categories filtered for that directory selection, and so on.)
{module_data resource="categories" version="v3" collection="directories" template="" where="\{'categoryTypeId':'42'\}" }
{module_data resource="categories" version="v3" collection="categories" template="" where="\{'categoryTypeId':'43'\}" }
{module_data resource="categories" version="v3" collection="subcategories" template="" where="\{'categoryTypeId':'140'\}" }
I wrote a JS function that does the showing and hiding of the filtered results from the prior selection.
My big problem is that today's update has removed that field.  Assuming that there is now no way to put this back in, I would love an explanation as to why this was removed, as this has caused me to suddenly have to re-architect a key component of the site's UI.
In addition, I would also appreciate any insights as to how this might be accomplished some other way (easily?) using the remaining fields and/or {categorylist}
Thanks,

Hi Bruce,
I am really sorry for this bug. We are going to reintroduce that field tomorrow till end of day. I do not know how the values where chosen for categoryTypeId but this another issue.
Again, I apologize for this issue.
