And it does generally although I have tried setting it (for your example
below) to {ybg} and it disappears. If I set it to [ybg], it does appear
in the exported latex. I haven't delved into the beamer export code in
a long while but it must be checking for constructs of the form [...] or
<...>, I would guess.
In any case, addressing your real question:

Well, the problem is that a beamercolorbox is *not* a block and does not
expect a title parameter. It actually expects only a colour (well, a
beamer colour structure, to be precise, such as the one you have
defined). What is /org/ expected to do with the entry you specify?
To achieve what you want (maybe, as I am not clear exactly what you want
;-), you should probably define a block *within* the beamercolorbox or
vice versa. For instance:
--8<---------------cut here---------------start------------->8---
** Frame 2 \\ where we will not use columns
*** ybg :B_beamercolorbox:
:PROPERTIES:
:BEAMER_env: beamercolorbox
:END:
**** Title :B_block:
:PROPERTIES:
:BEAMER_env: block
:END:
Please test this stuff!
--8<---------------cut here---------------end--------------->8---

It is not a bug, IMO.
Whether it should be a feature request or not is debatable. The syntax
is, at present, fairly straightforward in that the headline text becomes
the argument to the environment defined. What that environment does
with the argument is obviously up to the environment itself!
HTH,
