How we built it

Deprecate all fetches for scripts with invalid type/language attributes (removed)

Right now, the preload scanner will send fetches for script tags regardless of type/language, but the script will not execute when parsed. By deprecating the fetch, the preload scanner and the parser will have the same semantics, and we will not be initiating fetches for scripts we will not use. To work around this issue, declarative fetches using link preload should be used.
