Oh the ideal. At my last company, we had developed years ago an API layer that allowed outside developers to build plugins to our web app. We also created a market place in which these developers could host these plugins. It was an absolute constant headache trying to tease out the bugs that these plugins would introduce. They often slowed the app down to a halt, and because they’re so opaque, users would blame us for the slow experience. I suspect it was because of the fact that their performance impact was so difficult to hold accountable, plug-in developers were never incentivized to make their plugins performant and just hacked them together. And this is universal. Every app I’ve used with a sufficient amount of capability for extensibility will invariably suffer this problem. Slack and Figma also suffer from this issue after you’ve installed a bunch of plugins. They get really slow and bug out. It is inevitable: the more code you add to something, the worse it gets.
