Version 1.0.0+ expected Informer regression?

[WeetA34]

Describe the bug
Starting client 1.0.0, I noticed two things which have been reverted to a 5/6 years old versions:

• the informer interface doesn't "support" anymore ErrorCallback for on/off("connect", ...) and on/off("error", ...)
• the makeInformer function returns an Informer<T> instead of Informer<T> & ObjectCache<T>

Both things above have been introduced 3 years ago.
So, i was wondering if it's expected to have reverted these to an old version?

version 0.22.3

We definitely forked to produce the 1.0 branch a long time ago and not everything got ported between the branches while we had both active. Feel free to cherry-pick/port and send PRs.
