The newsrc.eld has never been pretty and it's never been a problem, AFAIK.
Not sure what's the "Gnus registry", so I can't comment on that.

It's just added complexity for a very unconvincing result.
I'd rather make `pp' faster, or if it's too difficult split it into
a "print-really-pretty" and "print-quickly-and-not-too-ugly".
