Similarly, instead of or including higher HATT you'll see a steeper glidepath.
On a similar note, if you ever see a non precision approach without a VDP published, it means there are obstacles protruding the protection area for a normal 3* glidepath, meaning depart the MDA at your own risk at night or IMC even with the runway clearly in sight.

Sat-based and AR approaches are making many of these a thing of the past. There are still plenty, like the examples given, but technology is starting to be leveraged. It started with those LPV approaches years ago to 250 and 200' minimums. Even at 300 feet you suddenly had capability at airports that had either nothing or crazy high mins. At some point RNAV RNP approaches using curving paths will be available to more aircraft and systems.
