Distrust eMudhra intermediate CA certificates due to security concerns in python-botocore

https://emudhra.we-have-a-problem.com/

botocore version 1.43.117 removed the Comodo AAA Certificate Services root CA to distrust eMudhra intermediate certificates:

Comment 1 Tomas Hoger 2026-10-29 11:32:12 UTC
I filed this bug even though I noticed the work on updates to version 1.43.117 are already in progress (albeit Koji builds are failing).  The reason for doing so is to ask if we can / should stop shipping or using bundled cacerts in botocore, and switch to using system CA bundle from ca-certificates via python-certifi (see bug 2563310 comment 1).
