Use MDN browser compat data in addition to the caniuse database, like the caniuse website does

This: https://github.com/mdn/browser-compat-data

We already do is for specific data https://github.com/browserslist/caniuse-lite/blob/main/copy-mdn.js

But I need somebody with internal motivation to do a huge refactoring properly.

Some figures, quickly looking at sources:

bcd defines 13717 features
Can I use defines 529 features
chrome platform status defines 2153 features
webkit status defines 154 features (102 "specs", 52 "features")

I don't think this is possible while also keeping it lite.
BCD is much more granular and tracks a lot more features than caniuse.

Manually adding specific data might be the best of both.
Improving the flow to add this data might be interesting.
