Hey Ray,

Yes it is, but the most secure parsing code is that which doesn't exist. 
I'm confident in the one I wrote for the new PE/COFF library, but if 
variables suit the need, I really would like to use them, even if it is 
only by a toggle. The new proposal (please check the chain with Mike) 
was adapted to preserve the old behaviour fully for any platform that 
wants it, permanently. Amaranth will very likely drop support for the 
PE/COFF section, either nicely with an upstream PCD, or not-so-nicely 
with maintaining patches to remove the functionality downstream.

In the same chain I outlined I'm sketching a new terse file format and 
I'd prefer to avoid any unnecessary data or parsing burden. The current 
library I am sketching privately is *much* smaller than both the current 
and the new PE/COFF library. The overall format in an UEFI context (no 
dynamic linking etc.) is at least as powerful as PE/COFF and pretty much 
always smaller than TE. I'd like to keep it that way. :)

Best regards,
Marvin
