IMO when it comes to collecting and publishing game errata, Catalyst Game Labs and Battletech are the gold standard benchmark.
Players on those forums regularly identify incorrect information and post on a rules question sub-forum. Mods answer those questions or decide errata is warranted. All errata is posted in the specific product errata sub-forum, and then routinely collected, compiled, and published for the player base. When CGL decides to do a new physical printing, they incorporate the latest errata for the new printing.
For example, I purchased the physical + PDF combo of Battletech Alpha Strike Commander's Edition, which at the time was the corrected second printing. Since that purchase back in 2019, I've automatically received the PDFs for ASCE's third and latest corrected fourth printing.
I'm sure there may be more details that I'm not aware of, but as a game consumer the end result is impressive.
Edit: In all fairness this is a bit like compairing apples to oranges, as Traveller and BT are two different types of tabletop gaming experiences with unique histories. But the point I'm attempting to make how errata can be collected and released.
