Re: point 2, I don't know how different that is for stable distributions — e.g. if you're running Debian stable you're in control of upgrades and you can go years without installing anything other than security updates if you want.
Re: point 1, I'm definitely aware of that need but the only cases I see it are commercial settings where people have contractual obligations for either software they're shipping or for supported software they've licensed. In those cases, I question whether saving the equivalent of one billable hour per year is worth not being able to say “We test on exactly the same OS it runs on”.
