The \pdfcatalog primitive is not broken, it's simply not present in mkiv
where we have a rather strict control over access to pdf resources.

Anyhow, i'll add an option to the upcoming beta (normally I only do such
weird features in paid projects). The thing is that it has to be hooked
into the regular mechanisms properly (numbering, conversion) and the
code in the mail you refer to is not ok (as it's hardcoded).

Concerning your example, control over numbers happens this way:

\definestructureconversionset[frontpart:pagenumber][][romannumerals]
\definestructureconversionset[bodypart:pagenumber] [][numbers]

\setupuserpagenumber[way=byblock]
\setupuserpagenumber[numberconversionset=pagenumber]

Index maybe.
