In every major project I've been involved in (and it's not terribly many, to be fair) things keeping us on previous versions were almost always libraries or other support software, rarely if ever was it the devs.

Really? For me, it has been almost exclusively management not wanting to invest the manpower necessary for the adoption.

If the technology stack allows it, I assume most passionate developers would develop rather with newer than older toolchains.

These might be two sides of the same coin - usually the reason there is a huge manpower requirement is because of the libraries and supporting tools.

Most developers want to use the newest and greatest, but are held back.
