I don't think this is a correct interpretation of the license.  You don't
have to change a package name to "plainly mark" the source as modified;
debian/copyright, changelogs, notices in the source files accomplish this.
This is done for packages all the time, not just for zlib.

What a shame!  I think you could have gone ahead in good conscience :)

And I don't see any reason we can't go ahead with this now!
