The current implementation of GnuPG creates OpenPGP certificates with
this preference listing:

     Compression: ZLIB, BZIP2, ZIP, Uncompressed

Are you suggesting that we change it to:

     Compression: Uncompressed, ZLIB, BZIP2, ZIP

or to:

     Compression: Uncompressed

?

Setting aside the question of defaults, for your own OpenPGP certificate
right now you can do this with any modern version of GnuPG, if you're
willing to poke at the command line with some arcana:

For the less severe change:

    gpg --edit-key $FINGERPRINT showpref 'setpref S9 S8 S7 S2 H10 H9 H8 H11 H2 
Z0 Z2 Z3 Z1'  save

For the more severe change:

    gpg --edit-key $FINGERPRINT showpref 'setpref S9 S8 S7 S2 H10 H9 H8 H11 H2 
Z0' save

then of course you'll need to re-publish the cert via whatever your
standard publication mechanism is (keyservers, WKD, keybase, etc).
