It's somewhat widely already in use for large events etc, so clearly it works.

Not for consumer products, but it's not optimized for those. If you buy any kind of professional NICs and switches, 1588 support isn't that hard to find. Wide support means less trouble if one manufacturer changes things, more choice in hardware than a proprietary system would likely have. Can live with existing networks.

E.g. lets say you're building out an event at a large convention center. They probably can give you Ethernet or fiber from one end of the building to the other, but can they give it to you for your proprietary thing of choice?

Or you are making a permanent installation: do you want to have to put one vendors stuff everywhere, as a parallel network of proprietary stuff, or do you prefer something that works on the network infrastructure you already have, with maybe some upgrades to some components, but keeping it with the stuff your network people already know? Especially if it means you don't need to pull additional cabling or fiber everywhere?
