some rhetorical questions (sad that i have to put a disclaimer about it):

1) will any of these changes increase real-world compatibility? can
you link to the code that would become executable on plan9 as a
result?

2) if not, will this improve any other real world program running on plan9?

3) if 1) or 2) is true, what is the cost of this change?

1)
no

2)
no

3)
it's a non-zero cost

and the benefit: zero.
