[openpgp] Re: Fwd: I-D list for Open Specification for Pretty Good Privacy notification: Changes to draft-gallagher-openpgp-code-point-exhaustion

[Heiko Schäfer <[e-mail]>]

Hello,

I'm sure much discussion would be needed to positively decide in favor 
of the scheme proposed in draft-gallagher-openpgp-code-point-exhaustion.

However, as I understand it, the only immediate question that this draft 
is effectively asking is: "do we want to reserve bit 8, for now?"

I have not seen any compelling argument against this proposition, so far.

So as a defensive stance, I'm in favor of "reserving bit 8" for all code 
points where this bit is still unused. At least until there is a 
compelling argument why the currently vacant second half of a particular 
code point space is required for some proposed new feature.

Thanks,
Heiko
