No. I think Laslo meant 'proprietary' as in 'ad hoc' or 'incompatible'
(with standard implementations).

While I generally agree with Laslo, I'm in favor of supporting *a
select few* of GNU tar's extensions.
Granted, most of them are pretty niche (insane), like support for
files that span over multiple volumes.
But there's at least one useful extension: Long file name support.
That extension is also what Cág's error message "unsupported
tar-filetype L" is about.
I'm pretty confident that, with this extension alone, you would be
able to at least extract most GNU tar archives.

I could try writing a patch for this, if people are interested.
