This is a welcome addition. Thanks!

Please also add etc/ORG-NEWS entry - it is org-element API change.

In addition to changes in Org git, you also need to update
https://orgmode.org/worg/org-syntax.html#Timestamps and
https://orgmode.org/worg/dev/org-element-api.html
(the page source is at https://git.sr.ht/~bzg/worg)

This will match timestamps like <2012-03-29 Thu +1y2y>. You may instead
use shy group \(?:...\)? around the whole /2y regexp match. (Or even
rewrite the regexp via rx for better readability, while we are on it).

This is slightly confusing, because "deadline" has multiple meanings in
Org. repeater-deadline-value/unit would be more readable as the variable name.
