Not really. If the FAA changes one character, then the software vendor
(e.g. SA) has to update all their programs or have some way to tell their
program where to find the actual data. It has happened before, and it'll
happen again. Things change a lot more often than you think - a well
designed program hides this from you.

I disagree. First of all, the optimal way to obtain the updates is from
the SA server, but they are compressed. You can obtain the uncompressed
diagrams from the FAA server. I can't recall whether the SA program
permits you to change the server address, but it would be ideal if it
did.
