High is only in the eyes of the beholder I guess.
When I started seventeen years ago, it was normal to keep 1.026 for a reef tank as that is what the majority of the ocean water is at, where our fish and corals come from.
Many hobbyists keeping fish only used water with less salt content for one reason or another, but the same hobbyists kept the s.g. at 1.026 for their reef tank because it was better for the inverts and corals.
Based on my years of reading the forums on RC, I believe that the majority of hobbyists are using at least 1.025 - 1.026.
