As a small note on this, we are still planning to have a fuller discussion
of compatibility after the publication of 4.0, including discussion of the
criteria for naming a license as compatible with BY-SA. However, we have
continued to be in contact with FSF about potential outward compatibility
with the GPL. We hope to update with more specifics soon, but our current
understanding is that the draft as it stands would not prevent this from
being possible.
