As someone who used to be in SaaS sales selling a complex platform, this might be the case for you if you're constantly doing a lot of research and keeping up with the market, but it's not for the vast majority of others. I can't tell you how many software engineers and leaders I cold called who thought our platform did one thing, but was surprised to learn we GA'ed a different capability, and then they'd mention they were talking about that with their team in standup recently, and then they'd take a meeting.
Again, not doubting there are people like you out there who stay up to date with vendors, but there was a lot of useful education being done in those cold call connects. That company still employs an army of BDRs doing the same thing today.
