LGTM, @dennishuo has now scared me of 503's and anonymous 409's (not thrown by the IRC) potentially causing issues but I think we can address that in a follow up if we get consensus. |

About the change
presently, we retry on 502 / 504 as well here, we have a spec definition stating here that when these status are thrown the commit status can be unknown, so says the RFC as something went wrong in the middle of processing the request. So we retry with 502 and 504 we can conflict with ourselves, as we don't know when we receive the status of 409 is it because we retried on 502 and then got 409 or something else happened, so it's better to throw the commit state unknown if we know the commit has been retried.
The Iceberg users who complained this was with 504 : slack thread - https://apache-iceberg.slack.com/archives/C025PH0G1D4/p1747992294134219
We have similar handling for glue as we did here #7198 as there are internal http retries over the glue SDK.
So I Added a PR considering above #12818
But based on offline discussions with more folks, according to the spec its best to not retry on 502 / 504 as it clearly calls out that the status is unknown.
The change attempts to :
