This, IMO, is where we differ.
Postel's Principle is more an application of Hanlon's Razor:
*Never attribute to malice that which is adequately explained by stupidity.
*http://quoteinvestigator.com/2016/12/30/not-malice/
(replace "stupidity" with "ignorance" or "accident" and the relationship
is more clear).
IMO, the Postel Principle advises two things:
- don't over react to ignorance/accident
- don't do things that make others question your motives
These principles apply both to protocol specification and
implementation. It's excessive to explicitly outlaw something that might
be useful and could occur benignly, UNLESS it creates a dangerous or
specifically incorrect result.
