You are free to not use a feature, but you must understand all when
using third party code. And the new features are neither easy to
understand nor to remember.

True.
But it adds quite a lot of stuff and a simple loop can become much
slower.

True. What about nested classes?

Correct me if I'm wrong, but all the alternatives in javascript have
some drawbacks, you don't write big programs in
javascript and the anonymous methods easily confuse the javascript
debuggers.

This feature made records more consistent with objects and classes, so
I would say they indeed made Pascal easier to understand.
