I strongly encourage you and others to ensure that PROJ.4 or other lightly
maintained packages are suitable for your purposes if you depend on them
in a mission critical fashion.  Frankly, the project is not adequately
resourced to ensure that all good software development practices are

Even better maintained packages (like GDAL for instance) still have lots
of dark corners that are buggy and not regression tested.

So, implicit or explicit claims of validation are always "relative".  Little
is really certain and you are wise to confirm things meet your needs.
