It's certainly a balance issue. Although hardcore raiders want more challenging content (and devs indeed wish to provide that), the echoes of Gordian Savage ring through the halls of SE, reminding them of what happens when content is made too difficult to the point where jobs are ruled out on a globally universal level. There's probably a desire to expand the percentage of players competing in savage content, which would lead to more reason for them to make that content easier while providing unending raids to keep the more consistent savage players content.

As for me personally, I don't really do savage mostly because I don't really care. Endgame for me is either extreme primals (usually against my will) or 24-player raids, because the most entertaining combat mechanic for me has always been the difficulty of getting 24 people to communicate.
