Hi all,
I would like to open this topic again, which was discussed few years ago [0]
and was not quite struck. Are there any news/plans?

Sorry, no.

One simple way forward would be to implement what pigz -tl does, namely, 
decompress the input stream and discard the output, but print its size. 
 It's slow, but it works and requires no change to the gzip format.  Is 
that something you could do?

We could do something fancier later, if we like.

That's not bad idea. However I think that general problem is speed for 
large archives in these days. But I understand that this is maybe best 
solution without change of gzip format.

May I will be able to work on patch, sometimes during next months, when 
I have time. I think that patch
should add new option, which will ignore field with input size data and 
get it as you described above.
So user will be able to set which method will be used.

I finally got around to implementing that suggestion:

https://git.savannah.gnu.org/cgit/gzip.git/commit/?id=cf26200380585019e927fe3cf5c0ecb7c8b3ef14
https://git.savannah.gnu.org/cgit/gzip.git/commit/?id=32fef43b442c7abc70414863d64718cd06f6477a

So I am closing this old bug report.
