I would actually vote against this idea if the forum still allowed that.
Reason: different ODS destinations have different needs. I would NOT want that for RTF, PDF or HTML (in various flavors).
Since the ODS Excel destination allows setting column widths as an option then it is under your control for Excel output.
I think you may have a very specific example in mind but you did not provide supporting reasons as to why or where this might be a desirable option to apply to "all output screens".
