He’s talking about my module. The difference between our modules is that your
use “10 \Meter \Per \Second” for the input while i use
”\siunit{10\meter\per\second}”.
There is nothing wrong about two modules with the same function as long as both
do not cause a problem for the module (and i took care of this in my module).
Parts like the number parsing can become part of the core and you provide a
function which others can use to integrate it in their own macros.

I’m not a friend of the ”m/s” input because you can’t say where a units
starts/ends without adding separators between them, here is a example from
latex’s siunitx package which supports both methods but although the first is
shorter we should rely on the tex method
- si{kg.m/s^2}
- si{\kilo\gram\metre\per\square\second}

Adding this function is no problem, synonyms can also be integrated in any
other system.
