Re: [openpgp] Deprecating compression support

Hello to you, too. Here is a parable:

Kleopatra goes into a Bar:
Kleo (linux): Hey look how small my archives are now using LZMA!!
Kleo (win): Uhm LZMA is that a disease? I don't know it!
KMail (linux): Ha, I have KArchive. K7Zip is the Best!
GpgOl (win): Uhm 7zip, does that mean that I have to unzip it seven times?
KMail (linux): No stupid, you just have to get your user to install additional 
software.
GpgOL (win): Awww. shucks. I thought we were user friendly nowadays.
GpgOL (win): Haha! But now!  I have winrar.
Kleo (linux): What? Winrar? "Win" and rar? go @!§13 yoursellf.
KMail (linux): Yeah KArchive can handle that.. *sunglasses*
Enigmail (win): Eh, guys I'm a crypto plugin, what are you talking about? I     
                        can no longer decrypt your messages! What are you 
doing?!!
Kleo (win): I can do ZIP! (Imagine Ralph Wiggum)

And even in this scenario how would they even communicate which compression 
algos are used. Because it is _not standartized_
OpenPGP has been around for ages. Software relies on the pecularities of it.
If I would have to design a cryptographic message format from scratch I 
probably also would not include compression in there.

But the existing software relies on that. We are not designing a new standard. 
We are designing an improvement on RFC4880.

I don't want to rewrite major parts of KMail / GpgOL / Kleopatra with some 
weird unstandartized custom compression stuff. It's a part of OpenPGP. IMO it's 
a good part.

It's nice that you guys have new ideas but we have literally millions and 
possibly billions of users already and we have to be f'''ing rock solid in our 
implementations and in our standards.


Best Regards,
Andre
