 -1 from me. I usually want to use a minimum of flags; the compiler
 messages help me switch them on in a controlled, deliberate sequence.

 Flags/pragmas around Overlaps and `IncoherentInstances` I would never want
 to be enabled automatically: if I've written instances needing
 incoherence, I've done something wrong.

 I echo @goldfire's suggestion to use the established process, not Trac, to
 get a wider opinion.
