Undocumented Scala 3 compiler options

[Bersier]

Several Scala 3 compiler flags seem to be undocumented.

For example, the only documentation I could find for -Wvalue-discard is on this page, which incorrectly starts with

This doc page is specific to features shipped in Scala 2, which have either been removed in Scala 3 or replaced by an alternative.

Another example is -Wnonunit-statement, which only seems to be unofficially documented in an announcement for Scala 2.13.9...

(Also, there doesn't even seem to be a documentation page for all Scala 3 compiler options.)

that would be correct because the page you linked was written for the scala 2 compiler and not updated yet for scala 3

if we don't want to completely restructure the page, we can either make a separate scala 3 page, a scala 3 section on the same page, or we could add tags to each option to say the supported versions, or we replace with a table, but that may take more effort
