Of course, it would. After all, we want two sides to be able to speak to 
each other, to create this Internet :-).

It's nice and stable as a technology stabilizes. But when the next thing 
needs to be built (400Gbps today, 800Gbps tomorrow, maybe 1Tbps in 5 
years or less), vendors like to compete on who can come up with the 
first (not the best) solution. Industry then catches up a while later.

Just look at what Cisco tried with the CPAK. While novel, didn't work 
out too well for them, and the customers that bought tons of them. But, 
fair point, CFP2 was still dithering, so...

We've seen the same with Apple, and how ship their devices with 
"unproven" tech. They've been lucky, so far...
