The reason I find it a bad approach is not that it is forbidden or 
explicitly discouraged (I agree that it isn't), but because of the use 
of indirections.

Yes, you can use the oven to store marmelade and sugar.  That is not 
forbidden or explicitly discouraged, but still odd.

...but then again: this time you didn't ask for my opinion ;-)

I suggest asking Daniel Kahn Gillmore.  Both about his opinion on 
introducing a new subpacket, and about the status of his RFC6091.

I'd rather you do it than me, as I expect you to much better be able to 
summarize to him what really is the issue here.
