When I get a font package with OTFs, should I also keep the Web versions?

I've just downloaded the Comic Neue font family distribution zip (from here ). It has an OTF/ subfolder with 12 .otf files, and a Web/ subfolder with 49 files - .ttf, .eot, .woff and .woff2 files (same 12 base-names as the OTFs). Is there any use for me - as a desktop user and even perhaps as a person creating raster and vector graphics, but _not_ for the web / mobile world - to keep the Web/ font files?
