Description
#52644 made it an error to specify a #![feature(...)]
that the compiler doesn't know about. It could be a deny-by-default lint instead. @varkor in #52644 (comment):
I don't see a strong reason not to make the unknown feature error a deny-by-default lint instead, which would allow you to silence it.
