I think the normal thing would be that an author develops package for a particular TeX format, but then again, such a package may well run under another format, and the author may not have the particular hardware/software needed to check it out. So why not \DesigedForTeXFormat{Foo} % Supported by developer \RunsUnderTeXFormat{Bar} % Unsupported, but seems to run "Unsupported" means that it runs under a particular TeX format, but an upgrade of the package may make that upgrade to not run any longer under that format. I thionk also that a more advanced package may want to choose its code depending on which TeX format it is run under, so one may want to have a command \IfTeXFormat{Foo}% {Do this stuff}% {Else do this stuff} One can then conditionally include the files needed under several different TeX formats.
