Well, you’re welcome to your opinion. :-)

The basic set of constraints seem very straightforward and, as always, 
operators are likely to lab test their configurations before a production 
deployment.  If FlexAlgo really takes off, it would imply that the vendors have 
good interoperability of those basic constraints.

Short of creating a worldwide authoritarian government with you as its 
benevolent dictator, what would you propose? :-)

There have been many prior attempts to ensure compliance and interoperability.  
There have been test suites and compliance statements. All of it has proven to 
be of dubious value. What has worked? Actual interoperability testing where 
developers sit down and test.  Today, that role seems to be primarily fulfilled 
by EANTC and FlexAlgo is already tested there.
