Does (or maybe can) RUPS use, report issues or display the Linearization data objects?

Currently RUPS does not display the Linearization data but I'm unsure if it uses, or always ignores it and uses the xref table, or some mix depending on how good/bad the data is.

It would be good if it could at least display the Linearization data in the GUI - and yes I know it is not "wired into" the PDF DOM.
If it could even validate / check the data and report issues in the "Debug Info" or "Console" windows that would be even better!

Thanks.
