I don't think it is needed for either command.

'git blame' has --porcelain and --incremental output, which is line-based
and pretty much self-describing (with "header-name value" syntax for most
of it), and well documented.  JSON output would only add unnecessary
chatter and different quoting rules.

'git for-each-ref' has both --format=<format> to allow to get data what
one needs, and in the format one wants (with e.g. %00 to reresent NUL),
and [--shell|--perl|--python|--tcl] for placeholders in <format> to be
quoted as string literals suitable for specified host language.  Although
I am not sure if this option, meant to produce scriptlets, is used that
much/ note that there is not support for --json quoting, nor --xml 
escaping.
