Probably, if you say why "that" is not included in the present distribution,
although it was included before, you are makeing pressure to the
developpers of Plan 9.   At least, they may feel so.

This is my proposal to them open.☺

You don't need to feel pressure, if it concerns with applications.
It is applications what make OS usable or attractive to ordinally
people like me.   However, all human has their own limits in given
abilities.
