"Read the tracker" is too general - what specifically are you looking for feed information about?

The datatracker has several feeds already, for instance, https://datatracker.ietf.org/feed/rfc.

Discoverability is difficult, but for the moment, tell me what you are looking for specifically, and I'll let you know if there's already a feed for that.

I would like to see information on the latest submissions

I don't see the RSS feed icon at https://datatracker.ietf.org/

If by submissions, you mean Internet-Drafts, there's not currently a feed. (There is a feed for RFCs already linked above).
I'll turn this issue into an enhancement request for a feed for recent Internet-Drafts, and for making feeds discoverable.

In the meantime, there is a page at https://datatracker.ietf.org/doc/recent that has the info you are looking for.

Internet-Drafts

yes

Paul - please add a feed for recent drafts (that returns the same documents that /doc/recent does) and propose a way to advertise the RSS feeds.

Subscribe Atom is more appropriate. The Atom Syndication Format
https://datatracker.ietf.org/doc/rfc4287/

RSS 2.0 is released under the copyright of Harvard University, to which Dave Winer ceded the rights in 2002. Since then, with the exception of minor corrections to the documentation, no modifications have been made to the format, and the specifications themselves emphasize that none are planned. It is left to developers to extend the format through modules while keeping the core aligned with the original standards.

Certainly, this situation has provided the basis for considering the creation of a subsequent format that, under a different name, could address the fundamental issues of the RSS 2.0 structure. One result of this evolution is Atom itself.

The development and design of Atom is fully transparent and oriented towards an open philosophy. Documentation and developments are managed through a wiki that is accessible and editable by any user. A central group is responsible for collecting and organizing these improvements, establishing the specifications of the format.

Consequently, Atom is a format that is still under development and is intended to continue evolving.
