I personally try to avoid symlinks (probably because I keep getting in trouble with them ) but right now I think the driver requires them for certain distro configurations. Much as I sympathize, I hope the Arch folks would not stop packaging fglrx just because of the requirement for symlinking.
That said, if they're moving to server 1.6 and we don't support 1.6 yet then packaging the driver for upcoming Arch versions doesn't make a lot of sense. Not sure if it's still worth packaging for users running older versions or if most Arch users run the latest bits anyways (ie there would be too few people running pre-1.6 to be worth the effort).
The only thing I didn't really understand was that the first part of each post basically said "we've stopped packaging because of technical issues" while the second half of each post said "we hope someone else will take over the packaging". I think that translates into "it's a pain in the butt so someone else should take it over", which is fair.
