What happens when an Installer script--not necessarily OWB's--overwrites your customized .info? That's not necessarily a drawback, but an installation routine should make an attempt to keep and upgrade a user's existing settings.

Use IFF? That's not a good solution either. Deficons is the compromise solution, yes? It all depends on what--operating system or application--owns data. System designers are still looking for the holy grail of application agnostic storage containers.
There are some aspects of .info files, like tool types, that are pretty cool. The downside, I think, is having to write wrappers to combine ReadArgs(), FindToolType(), and generic command-line processing in a way that works with multiple releases of Workbench.
