Prevent Typescript from checking entire classes to save time?

Typescript is taking a long time to run, so I used generateTrace from https://github.com/microsoft/TypeScript/pull/40063

It showed that most of the time was comparing complicated classes with their subclasses. E.g. one of the classes is the base Objection model (https://github.com/vincit/objection.js), which is the base class that all my models inherit.

E.g. I have code like:

class User extends Model {}

function doSomething(model: typeof Model) {}

doSomething(User);

I have ~50 models. I think the first time TS encounters each model is slow, then it caches it. It takes about 5s for TS to compare a specific model with the base Model. The Model uses types from several libraries. Here’s a screenshot of the trace, it takes 5min just to compare each model with Model:

Is there a way to get TS to stop comparing Model with itself? I.e. since User extends Model, there’s no need to check the fields it inherited.
