📝 Original message:Hi I have a small interjection about the point on error correction (excuse
me if it seems elementary). Isn't there an argument to be made where a
wallet software should never attempt to figure out the 'correct' address,
or in this case private key? I don't think it's crazy to suggest somebody
could import a slightly erroneous WIF, the software gracefully
error-corrects any problem, but then the user copies that error onward such
as in their backup processes like a paper wallet. I always hate to advocate
against a feature, I'm just worried too much error correcting removes the
burden of exactitude and attention of the user (eg. "I know I can have up
to 4 errors").
I'm pretty sure I read those arguments somewhere in a documentation or
issue tracker/forum post. Maybe I'm misunderstanding the bigger picture in
this particular case, but I was just reminded of that concept (even if it
only applies generally).
Thanks,
AJ West
