Aki is correct and is consistent with what I said in the video, although I could have phrased my explanation better.
"dsync" refers to the tool/utility (part of doveadm) that does mail synchronization between a source account to a destination account. As Aki said, this is not going anywhere. This is a necessary tool for any kind of migrations, for example. dsync is under active maintenance, as we heavily use this tool internally.
What is being removed is the replicator plugin (that used dsync). That's what is being referred to in the video. Replicator hasn't been actively maintained for years now so this was dead code anyway.
To answer the OP: sis is also being removed and should not be used by any new installation. Code remains to read data written by the old plug-in so that these installations don't require a migration between 2.3 and 2.4. This is another plugin that hasn't be actively maintained in years, and has all kinds of limitations that prevent it from running at scale.
Neither replicator nor sis is code that is moving from open to closed source. These plugins aren't used in Pro. They are unmaintained so they are being removed, as happens with any kind of old code.

FUD ?
I knew someone would accuse me of that which is why I linked to the video from the horse's mouth, I transcribe what the speaker said:
"there will be an open source version, but that open source version will be maintained for single server use only. we are actually taking out anything any actually kinda' involves multiple servers, dsync replication and err some other stuff. so dovecot will be a fully-featured single node server"

Dear Laura, please don't spread FUD that you made up.
Dsync is not going anywhere, and we are not close-sourcing Dovecot Core. There is not a trove of code going into Dovecot 3.0 that "never sees the daylight".
Thank you, Aki

TL;DR If you are a Dovecot Community user, don't waste your time reading the Dovecot Pro release notes.
To expand:
I think you have to understand that lots of things that are going into Dovecot 3 (Pro) will never see the light of day in the community edition.
In addition, Dovecot have publicly quite plainly announced in public that they are actively removing all multi-server related functionality from Dovecot Community.
I don't think the community has quite yet grasped it. Things like dsync will be GONE in the community version.
If you don't believe me, look at this video, about 15 minutes in: https://youtu.be/s-JYrjCKshA?feature=shared&t=912

Hi,
I am currently in the process of planning a new deployment of Dovecot. I was planning to use mdbox or sdbox with “mail_attachment_fs = sis posix”, but I stumbled across the following notice in the documentation for Dovecot 3.0
