To fix your scenario, the build system that is installing the wrong versions and blowing up is the nostalgic one. And yeah it has some optimizations but it also has a bunch of anti-optimizations at this point. The new one is annoyingly different to look at but it actually sets up the server correctly.
"Stay in your lane" is not the way to address any flaws in what the OP did.
Cooking is not merely chemistry. Historically, it is providing for one's family at the hearth, the until-very-recently physical center of the home. It is the natural progression from lactation; one still receives sustenance from the Mother.
OP divested the recipes of that traditional tie. It's as if OP mathematically designed a Christmas tree with optimal packing, using a 3-D printer: an imitation Christmas tree, but not something that will evoke those remembrances of being a five-year-old again.
Are you all reading your own comments? Their mother can keep using the old version if she wants. It literally doesn't matter.
It's an affront to tradition. And that's important to a lot of people. It happens not to be important to a lot of very inward-looking geeks here on HN, so I felt it was important to call out that disconnect upthread.
You can't show up to your elders with a pull request and performance data and expect them to accept it. That's a misunderstanding at a very fundamental level about What Family Cooking is For, socially.
It's a mixed bag, not a dummy barging in and ruining everything.
