You're welcome!

It was discussed on the mailing list recently (unfortunately, I do not
remember the conclusion, so, please search for it)

BTW, everyone is welcome to update and add *any* references to the
page! It currently lacks references for most of items.

References are really important, as they provide the context for the
change. They help people to undestand *why*.

Also, this work wouldn't be for vain, as the same references could go
in the community change list for 5.2 release.

Thank you!
Alexander.
