ISO 8601 appears to use a slightly different syntax for writing timespans. I
would not object if anyone added support for that.

I'm pretty sure a lot of people would initially be confused why anyone would
write time in meters, let alone those that might associate it with memory
units. In my subjective view (and I acknowledge that we have all been
educated in different ways), writing "1m" for a time quantity is meaningless
and an error.

Standards exist for these things, and we have a fine tradition for choosing
standards in favor of randomness.
