So, would you prefer explain json format on a single line - no indentation or whitespace whatsoever?

yes, - if you need pretty format - there is function json_pretty - any more styles is wrong on Postgres side.
 

This far it was only about whitespace, but it can be useful for tweaking other aspects of output, as I've mentioned before.

Postgres is database, not presentation server - it have to to any database operations, quickly as possible - and formatting is part of client side.

I can imagine the ability for 3rd-party code to override certain aspects of the output would be really useful for extensions or background workers, decoding plugins, etc.

we talking about output - I can imagine, so there is only two possibilities - plain join, and pretty formatted join (but with only one style).

Then what would you differently exactly?

simple code.
