very few people would need to be convinced to upgrade it to a better format

Only the tens of thousands of current users who I personally have who would see no reason to change something that currently works and is secure. I have, in fact, suggested a number of better solutions over the years.

Hell...it took us 10 years to convince all the third parties that plain FTP was probably a bad idea. And there's still a tiny handful of very, very large companies that still say 'meh' and force us to keep an FTP server around.

Must be nice to not have to deal with real customers.
