The following is an attempt to answer 2 of your questions. More knowledgeable individuals, in particular state/municipal authorities in the US, would be in a better position than I am to pursue the Q&A.
when do these addenda become 'enforceable' as part of the standard?
Enforcement (of what is/isn't part of the referenced Standard) has more to do with the authority (e.g., state/municipality, GSA, USGBC), than the Standard itself. My understanding is that, unless explicitly stated otherwise, authorities wouldn't consider addenda to a Standard as part of the Standard (I suspect this would be different for errata). Approved addenda make their way into the next iteration, as stated in the Standard foreword ("All approved addenda and errata are included in the new edition" and "More than 125 addenda to the 2013 edition of the standard were processed by the committee and approved by the ASHRAE and IES Boards of Directors and are incorporated into the 2016 edition.").
there is no way to know what all addenda could be added before the 2022 version is published
Here? or Techstreet's My Tracker? I get that it would be nice to have the option of selecting a date (or addendum) and have the Standard printed out as if it had integrated the addendum (similar to how CVS solutions like Git can show different states of a document when moving from one commit to another). A nice to have, maybe.
