If not derogatory, I have never found the "This is how ... was done in the 90s/80s/70s" sentiment to contribute much to a conversation.
If you genuinely disagree and believe the 90s were as ripe with quality tooling and documentation as 2016, well, that's a bit strange, but you're certainly entitled to your opinion.
The last thing our discipline needs is us thinking we got it all and it just needs polishing.
