Say you have a nice, older road bike, from the 5-6 speed era; Swapping in a 9-speed Tiagra/105 group with cassette wheels and STI shifters would be considered an upgrade, even though 9-speed is 'obsolete'

That’s all nice, but the OP has a Deore-level bike that is not even all that old. This is not some vintage frame with outdated parts.
