Can you conditionally include Services/Weather.php inside the various functions
of the block that need it (or in one loading method) and abort gracefully if
it's not there? That seems like the best path.

No, and they should be avoided if possible.

No. Commenting out the block is a valid option (and equivalent to conf.php
options for other things that require specific extensions).

Yup - Horde::logMessage() is a good idea.
