You're right. At the risk of sounding kind of hypocritical, after a decently long career in software engineering, I've learned that some carefully chosen future proofing is one of the things that makes a great developer and it's also something where one learns to eventually "see" where it is needed.

My "if nobody cared to mention..." part should have probably said "if nobody cared to mention, even after several specification meetings, that the software should be able to do X..." as I agree it's definitely part of your job to assess the needs.

This post is a bit weird though. It's as if someone is ranting about how hard it is to hammer nails into wood with a shoe or 15 other things, when you could just use a hammer.
