There are no accusations of tampering anywhere I can see, and it's
not about what I think.

This table is a key element in HPACK and therefore their provenance
should be documented, if nothing else for historys sake.

I found this email:

Which seems to be for a check-run to see if the current able should
be updated ?

It doesn't answer my question if HTTP/1 headers which cannot ever
be sent through HTTP/2 were filtered out before estimating the PDFs.

I'm thinking specifically of:

	"HTTP/1.1" (HTTP-Version in the status line)
	Reason-Phrases in the status line
	Connection: close
	Connection: keepalive
	Transfer-Encoding: chunked

None of these will pass through HTTP/2.0 and should therefore not
be used as training material for HPACK

Does anybody know if these headers were removed from the data-set ?

Never attribute to malice what can adequately be explained by incompetence.
