Meta of what? How is it convenient for streaming objects? Begin with 
access type. Proceed with time stamps.

There is nothing to debug in implementation of stream attributes. Nor it 
is helpful to debug communication logic issues because the format is 
*data representation* one. It represents *data*, not objects, not 
states. All vital information about the logic and state is not there. It 
is in the context. This is the main reason why *all* data representation 
formats are useless garbage even when binary.

Text basis helps to produce 100 to 1 overhead in payload which directly 
translates into latency, network and CPU load, storage space, packet 
overflows, variable-length packets where it should have been fixed, 
chunked transfers, dynamic memory allocation and mess that makes a 
64-core CPU to perform like an i286.

It is absolutely useless, you cannot read, browse, search real-life 
gigabytes long communication logs without customized tools.

Driving a car, heating the house, browsing Internet I do not care about 
the logs. The damn thing must work.

A requirement does not aid anything. It is just a requirement. JSON 
would not aid you in dealing with X.509 certificates. They are in ASN.1.

Lemming's argument. Everybody's jumping I am jumping too.

I am pretty much aware of data representation formats. Moreover, as you 
may have noticed I implemented lots of them. Not because it is fun, but 
because communication protocols is my job.
