Part of the problem is, engineers love shiny things.
Status pages are fundamentally boring things. Who wants to work on them?
It's always tempting to complicate something simple because in part "ooh shiny", and you can always find reasons to justify why. It takes some strong engineering leadership to effectively argue against complicating things, and not be just a constant pain in the arse to everyone and every thing.
The kinds of people that are that good, tend to be people that aren't going to want to do something so boring as build and maintain the infrastructure for hosting status pages.
