If a person can backup or explain their use of terms like 'the design perspective' with appropriate nuances, it's not bullshit.

If they can't, then sure, they're bullshitting you.

That's not to say the simplified version of the rule isn't useful though. It can save us from forever explaining x years of experience to everyone we encounter, as well as potentially confusing people new to the subject. Teachers do this a lot, intentionally.
