The OpenBSD project doesn't have the resources to provide this so m:tier employs a couple of OpenBSD developers to provide this option for people who want it. Not sure what is embarrassing about this.
The fact that virtually every other nix system, large and small, can provide this standard functionality, and the OpenBSD project cannot. Having to rely on third parties for convenient updates is an obvious potential security issue. Firstly because it discourages updates in the first place, but secondly because I now have to trust m:tier as well as the OpenBSD devs.
That is why I say embarrassing - they are one of very few projects to lack this feature, and this feature is an important part of a secure system. OpenBSD is all about being "hands off" and "sane by default" and yet paradoxically their update process is much more involved and hands-on!
If openbsd developers do it, why don't they make it official and provide it from openbsd.org? They could still plaster "this is thanks to funding from mtier" on the site prominently.
The OpenBSD developers are unwilling to do anything that makes some architectures better than others, and M:Tier is unwilling to build stable updates for everything. Perhaps this will change one day as hardware continues to consolidate, but that's the way it is for now.
