RSS creation in 4.x

Since RssHelper is deprecated, will there be another tool / plugin do perform the same task ?
Do helpers still exist in 4.x ?
If yes, will the helper be updatable ?

Yes, read

Ok, reading for the week-end.
Thank you.

Other problem with RSS feed (still 3.x) :
Why do dates always appear in English ?
Why entities do not get interpreted ?
