a single format for both python-based checks and traditional plugins
requires converting the output and exitcode of the latter. This probably
adds a lot more cycles.

The result of a plugin is a string, single-line or multiline.

The output string is just "decoration" from Nagios' perspective, the crutial
attribute of a check is the exit code. Nagios can work without outputs, but
not without exit codes.
In order to be usable with Nagios there must be something like
if __name__ == '__main__':
# runs as standalone python program
plugin = Class...
print plugin.output + '|' + plugin.perfdata
exit plugin.exitcode
so the file can be "imported" and cached by a Shinken poller and executed by
a Nagios. (similar to ePN)

Of course.
The de facto way to handle performance data is pnp and pnp wants strings. I
see no reason to store perfdata in any datatype except a string. The Shinken
core doesn't care for performance data except passing them to external tools
where they are processed. Also database backends (ndo, merlin) want strings.
