David Thrane Christiansen suggested to categorize extensions into<br>
Experimental, Mature, Deprecated and Legacy, and add warning flag to<br>
GHC that allow users to be warned about (or shouted at for) using such<br>
extensions, if they choose so.<br>

Because of the meta-like aspect of this proposal, I’d like to assign<br>
