It was not about 'do it yourself', but commodity for average users to
deal with it ...

It's again about existing tools/storage systems -- they have built-in to
access json as an object/variable, no need to parse yourself and build a
custom/own query language. Just for example, iirc, at some point I saw a
patch/presentation that MariaDB can do optimized searching withing json
object by matching with dedicated functions (as well as capability of
setting just a value inside json docs).

That will required development in all these systems, both can be seen as
serialization mechanisms, but their structure is different, so existing
json functions in one system cannot be reused.

You implemented and it was your decision, so I don't have anything
against using bencode in this case -- in the light of requests for
comments you asked for, I tried to figure out if parsing faster bencoded
strings pays off when balancing with the need to interact with/from
different components in a complete operational platform.
