OK, though this looks rather low-level. I was thinking about something
more user-friendly;).
This raises a philosophical question: is it the "ConTeXt way" to use
low-level constructs in environments and high-level in documents? Or is
it better to avoid low level whenever possible? Also, your code mixes
low-level commands (\vbox, which is a TeX prmitive, \raggedcenter, which
is a ConTeXt low-level command, I guess) and high-level ones (\blank).
I understand that this ensures a uniform vertical spacing (\blank[big]
is obviously better than \vskip 10pt;)), but I thought that it is
against ConTeXt philosophy to use low-level stuff unless something
really non-standard is needed.

Sorry, I haven't provided one. Here you are.
\starttext
\dorecurse{12}{%
This is some intro (\recurselevel).
\startitemize[n,packed,joinedup,columns,two,intro]
\dorecurse{8}{\item This is an item.}
\stopitemize
}%
\stoptext
(strange things happen both in MkII and MkIV in the online ConTeXt!)

But how do I control the stretchability?
